Question

A) Estimate the value of 98.5x13

b) Estimate the value of 102.3/4.7

Answer 1

Answer: A=1000

B=20

Step-by-step explanation: you can estimate that 98.5x13 is 100x10 and you can also estimate that 102.3 / 4.7 is 100/5

Answer 2

a) The estimated value of 98.5 x 13 is 1280.5.

b) The estimated value of 102.3 / 4.7 is 21.77.

a) To estimate the value of 98.5 × 13:

Estimate= 98.5 × 13 = 1280.5

This is a quick approximation by rounding 98.5 to 100 for simplicity.

b) To estimate the value of 102.3 / 4.7:

Estimate = 100/ 5 =20

This is a quick approximation by rounding 102.3 to 100 and 4.7 to 5 for simplicity.
