Multiply 4/9 by −3. Write the answer as a mixed number in simplest form
To multiply 4/9 by -3, multiply the numerators together and multiply the denominators together:
4/9 × -3 = (4 × -3) / (9 × 1) = -12/9
To simplify the fraction, find the greatest common divisor (GCD) of 12 and 9, which is 3. Divide both the numerator and denominator by the GCD:
(-12 ÷ 3) / (9 ÷ 3) = -4/3
Now, to write the answer as a mixed number, divide the numerator (-4) by the denominator (3):
-4 ÷ 3 = -1 remainder 1
Therefore, the product of 4/9 and -3 as a mixed number in simplest form is -1 1/3.
4/9 × -3 = (4 × -3) / (9 × 1) = -12/9
To simplify the fraction, find the greatest common divisor (GCD) of 12 and 9, which is 3. Divide both the numerator and denominator by the GCD:
(-12 ÷ 3) / (9 ÷ 3) = -4/3
Now, to write the answer as a mixed number, divide the numerator (-4) by the denominator (3):
-4 ÷ 3 = -1 remainder 1
Therefore, the product of 4/9 and -3 as a mixed number in simplest form is -1 1/3.
Multiply 2/3 by 1 1/4. Write the answer in simplest form
To multiply 2/3 by 1 1/4, convert the mixed number 1 1/4 to an improper fraction.
1 1/4 = (1 * 4 + 1) / 4 = 5/4
Now, multiply the given fractions:
2/3 * 5/4 = (2 * 5) / (3 * 4) = 10/12
To simplify the fraction, find the greatest common divisor (GCD) of 10 and 12, which is 2. Divide both the numerator and denominator by the GCD:
(10 ÷ 2) / (12 ÷ 2) = 5/6
Therefore, the product of 2/3 and 1 1/4 in simplest form is 5/6.
1 1/4 = (1 * 4 + 1) / 4 = 5/4
Now, multiply the given fractions:
2/3 * 5/4 = (2 * 5) / (3 * 4) = 10/12
To simplify the fraction, find the greatest common divisor (GCD) of 10 and 12, which is 2. Divide both the numerator and denominator by the GCD:
(10 ÷ 2) / (12 ÷ 2) = 5/6
Therefore, the product of 2/3 and 1 1/4 in simplest form is 5/6.
Multiply 9.6 by 0.2. Write the answer as a decimal
To multiply 9.6 by 0.2, we multiply the whole numbers together and then multiply the decimal parts together:

To multiply -25 by 310, multiply the absolute values of the numbers and change the sign to negative:
|-25| * |310| = 7750
Since the signs of the original numbers are different, the product is negative.
Therefore, the product of -25 and 310 is -7750.
|-25| * |310| = 7750
Since the signs of the original numbers are different, the product is negative.
Therefore, the product of -25 and 310 is -7750.

To multiply 4 by -5/8, multiply the whole number (4) by the numerator of the fraction (-5) and keep the denominator (-8) unchanged.
4 * (-5) = -20
So the resulting product is -20.
To write this as a mixed number in simplest form, we divide the absolute value of the product (20) by the denominator (8).
20 ÷ 8 = 2 remainder 4
Therefore, the mixed number in simplest form is -2 4/8. However, we can simplify this fraction further by dividing both the numerator and denominator by the greatest common divisor (GCD) of 4 and 8, which is 4.
(-2 * 4)/ (8 * 4) = -8/32
Now, divide the numerator (-8) by the denominator (32):
-8 ÷ 32 = -1/4
So the final answer, written as a mixed number in simplest form, is -2 1/4.
4 * (-5) = -20
So the resulting product is -20.
To write this as a mixed number in simplest form, we divide the absolute value of the product (20) by the denominator (8).
