To solve -1.7 / 2 1/2, first convert the mixed fraction 2 1/2 into an improper fraction.
2 + 1/2 = 5/2
Now, we can rewrite the expression as:
-1.7 / 5/2
To divide fractions, we invert the second fraction (5/2) and multiply:
-1.7 * 2/5 = (-1.7 * 2) / 5 = -3.4 / 5
Lastly, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 0.2:
(-3.4/0.2)/(5/0.2) = -17/1 = -17
Thus, the answer is -17. However, it is written in the form "-17," which can also be represented as "-17/1" or "-17 0/1."
Therefore, the correct answer, written in the simplest form, is -17.

To solve -1.7 / 2 1/2, we first need to convert the mixed fraction 2 1/2 into an improper fraction.
2 + 1/2 = 5/2
Now, we can rewrite the expression as:
-1.7 / 5/2
To divide fractions, we invert the second fraction (5/2) and multiply:
-1.7 * 2/5 = (-1.7 * 2) / 5 = -3.4 / 5
Now, to write the answer as a mixed number in the simplest form, we need to convert the improper fraction -3.4/ 5 back into a mixed number.
To do this, we divide the numerator (-3.4) by the denominator (5):
-3.4 ÷ 5 = -0.68
Now, we convert -0.68 into a mixed number by separating the whole number part and the fractional part:
-0.68 = -0 in the whole number part and 68/100 in the fractional part
To simplify the fraction 68/100, we can divide both the numerator and denominator by their greatest common divisor, which is 4:
68/4 ÷ 100/4 = 17/25
Thus, the final answer is:
-0 + 17/25
Which can also be written as:
-17/25
Therefore, the correct answer, in the simplest form as a mixed number, is:
-0 17/25
or
-0 17/25
2 + 1/2 = 5/2
Now, we can rewrite the expression as:
-1.7 / 5/2
To divide fractions, we invert the second fraction (5/2) and multiply:
-1.7 * 2/5 = (-1.7 * 2) / 5 = -3.4 / 5

-3.4 ÷ 5 = -0.68
Now, we convert -0.68 into a mixed number by separating the whole number part and the fractional part:
-0.68 = -0 in the whole number part and 68/100 in the fractional part
To simplify the fraction 68/100, we can divide both the numerator and denominator by their greatest common divisor, which is 4:
68/4 ÷ 100/4 = 17/25
Thus, the final answer is:
-0 + 17/25
Which can also be written as:
-17/25
Therefore, the correct answer, in the simplest form as a mixed number, is:
-0 17/25
or
-0 17/25

Apologies for the mistake in the previous response. Let's solve the expression correctly.
To multiply -1.7 by 2 1/2, we first need to convert the mixed fraction 2 1/2 into an improper fraction.
2 + 1/2 = 4/2 + 1/2 = 5/2
Now, we can rewrite the expression as:
-1.7 * 5/2
To multiply decimals and fractions, we can rewrite -1.7 as -17/10:
-17/10 * 5/2
Multiplying the numerators (-17 * 5) and the denominators (10 * 2), we get:
-85/20
Now, let's simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5:
(-85/5)/(20/5) = -17/4
Therefore, the correct answer in the simplest mixed number form is:
-4 1/4
To multiply -1.7 by 2 1/2, we first need to convert the mixed fraction 2 1/2 into an improper fraction.
2 + 1/2 = 4/2 + 1/2 = 5/2
Now, we can rewrite the expression as:
-1.7 * 5/2
To multiply decimals and fractions, we can rewrite -1.7 as -17/10:
-17/10 * 5/2
Multiplying the numerators (-17 * 5) and the denominators (10 * 2), we get:
-85/20
Now, let's simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5:
(-85/5)/(20/5) = -17/4
Therefore, the correct answer in the simplest mixed number form is:
-4 1/4

To multiply -9 1/2 by 0.04, we first need to convert the mixed fraction -9 1/2 into an improper fraction.
-9 + 1/2 = -18/2 + 1/2 = -17/2
Now, we can rewrite the expression as:
(-17/2) * 0.04
To multiply a fraction and a decimal, we can rewrite 0.04 as 4/100:
(-17/2) * (4/100)
Multiplying the numerators (-17 * 4) and the denominators (2 * 100), we get:
-68/200
Now, let's simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:
(-68/2)/(200/2) = -34/100
Therefore, the correct answer is -34/100, which can be written as -0.34 in decimal form.
So, the correct option is:
-0.38
-9 + 1/2 = -18/2 + 1/2 = -17/2
Now, we can rewrite the expression as:
(-17/2) * 0.04
To multiply a fraction and a decimal, we can rewrite 0.04 as 4/100:
(-17/2) * (4/100)
Multiplying the numerators (-17 * 4) and the denominators (2 * 100), we get:
-68/200
Now, let's simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:
(-68/2)/(200/2) = -34/100
Therefore, the correct answer is -34/100, which can be written as -0.34 in decimal form.
So, the correct option is:
-0.38

To determine which fish Sasha chose, we need to calculate the cost per pound of the fish options and compare it to the cost for the amount of fish Sasha bought.
Let's calculate the cost per pound of each fish:
- Salmon: $9.60/lb
- Whitefish: $7.20/lb
- Swordfish: $8.40/lb
- Haddock: $6.90/lb
Next, we will divide the total cost of $5.40 by the weight of the fish Sasha bought, which is 3/4 lb:
$5.40 / (3/4) lb
To divide by a fraction, we multiply by the reciprocal of that fraction:
$5.40 * (4/3) lb = ($5.40 * 4) / 3 lb = $21.60 / 3 lb = $7.20/lb
The cost per pound of the fish Sasha bought is $7.20, which matches the cost per pound of the Whitefish.
Therefore, Sasha chose the Whitefish.

To determine the balance of the contestant's prize money, we need to calculate the amount deducted for each wrong answer and multiply it by the number of wrong answers.
The amount deducted for each wrong answer is $12.50.
The contestant has answered 6 questions wrong.
To find the total prize money deducted, we multiply the amount deducted per wrong answer by the number of wrong answers:
Prize money deducted = $12.50 x 6 = $75
Since the contestant loses $12.50 for each wrong answer, the total prize money deducted is $75.
Therefore, the balance of the contestant's prize money is a loss of $75.
