What is two and five eighths minus one and one half

So first you convert

2 and 5/8 and

1 and 1/2

2 and 5/8=16/8+5/8=21/8

1 and 1/2=2/2+1/2=3/2

so 21/8-3/2

convert so that the denominator (bottom number) is the same

21/8 - ([3/2][4/4])

21/8-12/8

9/8=1 and 1/8

This is 2 and 5/5 - 1 and 1/2. The answer is 9/8 or1.125
