Bingel [31]

Answer: 11/16

<u>Turn 1 7/8 into an Improper Fraction</u>

Multiply 1×8 and get 8. Now add 7 and get 15.

1 7/8 = 15/8

<u>Turn 2 8/11 into an Improper Fraction</u>

Multiply 2×11 and get 22. Now add 8 and get 30.

2 8/11 = 30/11

<u>Do Keep Change Flip</u>

Keep: 15/8

Change ÷ into ×

Flip: 30/11 into 11/30

Your New Problem: 15/8×11/30

<u>Multiply</u>

15/8×11/30=165/240

<u>Simplify</u>

165/240÷15/15=11/16
