Question

ghazi · Answer

simplify 41 5/8 first

ghazi · Answer

$$41\frac{ 5 }{ 8 }=\frac{ 41*8+5 }{ 8 }=\frac{ 328+5 }{ 8 }=\frac{ 333 }{ 8 }$$

ghazi · Answer

and then $$43-\frac{ 333 }{ 8 }$$

anonymous · Answer

1 3/8

bbb911 · Answer

okay im confused is it 1/8 or 1 3/8

bbb911 · Answer

wouldn't it be 36 1/4?

anonymous · Answer

It needs 1 3/8 inches (meaning 1.375) to make both crutches equal.

bbb911 · Answer

but how would i get that answer?

anonymous · Answer

First 5/8 = .625, right? So 41 5/8 = 41.625.

Then 43 - 41.625 = 1.375.  Now you need to convert it to a fraction -- 1 375/1000 = 1 3/8.  Hope it helps? :\
