PLEASE HELP QUICKLY : find the sum and difference of 5/6 and 1/2
choli [55]

Hello!

The sum of 5/6 and 1/2 is 1 1/2

5/6 > 3/4 so round it to 1.

1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.

Estimating:

1 + 1/2 = 1  1/2

The difference of 5/6 and 1/2 is 1/2

5/6 > 3/4 so round it to 1.

1/4 ≤ 1/2 ≤ 3/4 so round it to 1/2.

Estimating:

1 - 1/2 = 1/2

Hope this helps!
