Answer 33

7.4 - (-3.7) simplifies to:

7.4 + 3.7 = 11.1

Answer 34

4 - 114 + 12 equals -98.

Answer 35

To evaluate 4 - 1 1/4 + 1/2, we first need to convert 1 1/4 and 1/2 to improper fractions:

1 1/4 = (1 * 4 + 1) / 4 = 5/4
1/2 = 1/2.

Now we can simplify the expression:

4 - 5/4 + 1/2

First, we need a common denominator for 5/4 and 1/2, which is 4. So we multiply 5/4 by 1 (4/4) and 1/2 by 2 (2/2):

4 - (5/4 * 4/4) + (1/2 * 2/2)
= 4 - 20/16 + 2/4
= 4 - 20/16 + 8/16
= (4 - 20 + 8) / 16
= (-8 + 8) / 16
= 0 / 16
= 0.

Therefore, 4 - 1 1/4 + 1/2 equals 0.

Answer 36

Apologies for the mistake. Let's evaluate the expression correctly:

4 − 1 1/4 + 1/2

To simplify, we first convert 1 1/4 to an improper fraction:

1 1/4 = (4 * 1 + 1) / 4 = 5/4

Now we can substitute the values into the expression:

4 − 5/4 + 1/2

To add or subtract fractions, we need a common denominator. In this case, the common denominator is 4. So we multiply 5/4 by 1 (4/4) and 1/2 by 2 (2/2):

4 − (5/4 * 4/4) + (1/2 * 2/2)
= 4 − 20/16 + 2/4
= 4 − 20/16 + 8/16
= (4 * 16 - 20 + 8) / 16
= (64 - 20 + 8) / 16
= 52/16
= 13/4.

Therefore, 4 − 1 1/4 + 1/2 equals 13/4.

Answer 37

To convert the improper fraction 13/4 to a mixed number, we divide the numerator (13) by the denominator (4) and express the remainder as a fraction.

Dividing 13 by 4 gives us a quotient of 3 with a remainder of 1.

Thus, 13/4 as a mixed number is 3 1/4.

Answer 38

75.5 - 32.55 equals 42.95.

Answer 39

-86.4 + 16.38 equals -70.02.

Answer 40

7.829 - 3.21 simplifies to:

4.619

Answer 41

To find the value of the expression -6 4/9 - 1 1/3, we first need to convert the mixed numbers to improper fractions:

-6 4/9 = (-6 * 9 + 4) / 9 = (-54 + 4) / 9 = -50/9
-1 1/3 = (-1 * 3 + 1) / 3 = (-3 + 1) / 3 = -2/3

Now we can substitute the values into the expression:

-6 4/9 - 1 1/3
= -50/9 - 2/3

To add or subtract fractions, we need a common denominator. In this case, the common denominator is 9. So we multiply -2/3 by 3/3 (which is equivalent to 1):

-50/9 - (2/3 * 3/3)
= -50/9 - 6/9

Now we can subtract the fractions:

= (-50 - 6) / 9
= -56/9

Therefore, the value of the expression -6 4/9 - 1 1/3 is -56/9.

Answer 42

To convert -56/9 to a mixed number, we need to divide the numerator (-56) by the denominator (9) and express the remainder as a fraction.

Dividing 56 by 9 gives us a quotient of -6 with a remainder of 2.

Thus, -56/9 as a mixed number is -6 2/9.

Answer 43

Apologies for the mistake. Let's calculate the correct mixed number representation of -56/9:

The division of -56 by 9 gives a quotient of -6 with a remainder of -2.

Therefore, -56/9 as a mixed number is -6 2/9.

Answer 44

The closest mixed number to -6 2/9 is D: -5 1/9.

Answer 45

To find the sum of -3/2 and 8/5, we need to have a common denominator. We'll use 10 as our common denominator.

Converting -3/2 to have a denominator of 10:
-3/2 = -15/10

Converting 8/5 to have a denominator of 10:
8/5 = 16/10

Now we can add the fractions:
-15/10 + 16/10 = 1/10

Therefore, the sum of -3/2 and 8/5 is 1/10.

Answer 46

The value of the expression -17.03 + (-17.204) is -34.234.

Answer 47

Answer 50

The expressions that represent a number greater than 1 are:

A. 23 × 5
C. 53 × 18

Answer 51

11.1 ÷ 3 = 3.7

Answer 52

To find the circumference of the miniature car tire, we can use the formula C = πd, where C is the circumference and d is the diameter.

Given that the diameter of the miniature tire is 1.468 inches, we can calculate the circumference as:

C = πd
C = 3.14159 * 1.468
C = 4.61607712 inches

Rounding to the nearest tenth, the circumference of the miniature tire is 4.6 inches.

Answer 53

To find out how many times greater the circumference of the full-size car's tire is compared to the miniature car's tire, we can divide the circumference of the full-size tire by the circumference of the miniature tire.

Circumference ratio = (Circumference of full-size tire) / (Circumference of miniature tire)

Circumference of full-size tire = 65.97 inches
Circumference of miniature tire = 4.6 inches

Circumference ratio = 65.97 / 4.6 ≈ 14.34

Therefore, the circumference of the full-size car's tire is approximately 14.34 times greater than the circumference of the miniature car's tire.

Answer 54

4.4196 ÷ 3.81 = 1.159257221

Answer 55

To multiply -4 1/2 by 1 2/5, we need to convert the mixed numbers to improper fractions:

-4 1/2 = -9/2
1 2/5 = 7/5

Now we can multiply the fractions:

(-9/2) * (7/5) = -63/10

Therefore, -4 1/2 x 1 2/5 equals -63/10.

Answer 56

To convert -63/10 to a mixed number, we divide the numerator (-63) by the denominator (10) and express the remainder as a fraction.

Dividing 63 by 10 gives us a quotient of -6 with a remainder of -3.

Thus, -63/10 as a mixed number is -6 3/10.

Answer 57

To multiply -3/8 by -1 2/3, we first need to convert the mixed number to an improper fraction:

-1 2/3 = (-1 * 3 + 2) / 3 = (-3 + 2) / 3 = -1/3.

Now we can multiply the fractions:

-3/8 * -1/3 = 3/8 * 1/3 = 3/24.

Simplifying 3/24 gives us 1/8.

Therefore, -3/8 × -1 2/3 equals 1/8.

Answer 58

I apologize for the mistake. Let's correct the calculation:

To multiply -3/8 by -1 2/3, we convert the mixed number to an improper fraction:

-1 2/3 = (-1 * 3 + 2) / 3 = (-3 + 2) / 3 = -1/3.

Now we can multiply the fractions:

-3/8 * -1/3 = (3 * 1) / (8 * 3) = 3/24.

Simplifying 3/24 gives us 1/8.

Therefore, -3/8 × -1 2/3 equals 1/8.

Answer 59

-62 × -8 equals 496.
