Estimate the difference by rounding each number to the nearest half or whole. 8 1/16 - 2 5/8

When should we round up?

-When the last digit is 5 or more

When should we round down?

- When the last digit is 4 or less

For 8 1/16, we need to round down to the nearest whole because 1/16 is closest to 0.

For 2 5/8, we need to round down to the nearest half because 5/8 is closer to 4/8 than it is to 8/8.

8 - 2 4/8

64 / 8 - 20/8

44 / 8 = 5 4/8 = 5 1/2

Hope this helps! :)

step-by-step explanation:

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
