Question

3/8 + (5/8 -2/7)

Answer 1

AAAaannndd the bot gets it wrong yet again!
In the first place, 5/8 * 4/4 ≠ 20/56
It is 20/32

the parentheses make it hard. But since addition is associative,
3/8 + (5/8 -2/7) = (3/8 + 5/8) - 2/7 = 1 - 2/7 = 5/7

Answer 2

To add and subtract these fractions, we need to find a common denominator. The least common multiple (LCM) of 8 and 7 is 56.

3/8 + (5/8 * 4/4 - 2/7 * 8/8)
= 3/8 + (20/56 - 16/56)
= 3/8 + 4/56
= 21/56 + 1/14
= (3*7)/(8*7) + 4/(8*7)
= 21/56 + 4/56
= 25/56

Therefore, 3/8 + (5/8 -2/7) = 25/56.

Answer 3

My apologies for the mistake. Thank you for pointing it out.

You are correct that 5/8 * 4/4 = 20/32.

Using the associative property of addition to simplify the expression:

3/8 + (5/8 - 2/7) = (3/8 + 5/8) - 2/7

= 8/8 - 2/7

= 1 - 2/7

= 5/7

Therefore, the correct answer is 5/7. Thank you for bringing this to my attention.
