Answer:

3.2 kg heavier than jeff

Answer:

48 3/4 - 45 1/4 = 7/2 or 3 1/2 = 3.5

Spelled result in words is seven halfs (or three and one half).

Step-by-step explanation:

Conversion a mixed number 48 3/4 to a improper fraction: 48 3/4 = 48 3/4 = 48 × 4 + 3/4 = 192 + 3/4 = 195/4

To find a new numerator:

a) Multiply the whole number 48 by the denominator 4. Whole number 48 equally 48 * 4/4 = 192/4

b) Add the answer from previous step 192 to the numerator 3. New numerator is 192 + 3 = 195

c) Write a previous answer (new numerator 195) over the denominator 4.

Forty-eight and three quarters is one hundred ninety-five quarters

Conversion a mixed number 45 1/4

to a improper fraction: 45 1/4 = 45 1/4 = 45

× 4 + 1/4 = 180 + 1/4 = 181/4

To find a new numerator:

a) Multiply the whole number 45 by the denominator 4. Whole number 45 equally 45 × 4/4 = 180/4

b) Add the answer from previous step 180 to the numerator 1. New numerator is 180 + 1 = 181

c) Write a previous answer (new numerator 181) over the denominator 4.

Forty-five and one quarter is one hundred eighty-one quarters

Subtract: 195/4 - 181/4 = 195 - 181/4 = 14/4 = 2 × 7/2 × 2 = 7/2

in Lowest term7 ÷ 2 = 3 1/2
