Use rounding to estimate the product

question: 4 3/4 * 7 2/17

a. about 28

b. about 32

c. about 35

d. about 40

The estimate of the product is about 35 answer C

Step-by-step explanation:

- We use rounding to estimate the product of two fractions

- The mixed number has whole number and fraction

- To round the mixed number we look to the fraction

- If the numerator is half or greater than half the denominator, then we

  add the whole number by 1 and cancel the fraction

- If the numerator is less than half the denominator, then we keep the

  whole number as it and cancel the fraction

- Ex: If the mixed number is , 3 is more than

 half 4 then we will add 2 by 1 and cancel the fraction part, the

 mixed number after rounding is 3

- Ex: If the mixed number is , 1 is less than

 half 4 then we will keep 5 as it and cancel the fraction part, the

 mixed number after rounding is 5

* Lets solve the problem

∵ In the part 3 is more than half 4

∴ The rounding value of is 5

∵ In the part 2 is less than half 17

∴ The rounding value of is 7

∴

* The estimate of the product is about 35

i think the answer is seven, for if i'm being useless °ω°

step-by-step explanation:

the answer is 8/21
