Question

the recipe requires 3 1/4 cups of flour. radha has 1 3/8 cups of flour . how many more cups of flour does she need

Answer 1

3 1/4=(3*4+1)/4=13/4
and 1 3/8= 11/8 (do as given above)
so total= 13/4
and she have 11/4
so 13/4 - 11/4 =required cup of floors
so after taking LCM of 4 and 8 we got 8 
so after changing it we get
= 13*2/4*2
=26/8
and she have 11/8
so subtract it 26-11/8
15/8 or 8 7/1 ans
