Question

you spent 1 whole 1 by 2 hours on homework last night and 1 by 4 of that time was spent on mathematics what fraction of an hour did you spent on mathematics​

Answer 1

Total time spent on homework  =  1 $\frac{1}{2}$  =  $\frac{3}{2}$  hours

Time spent on maths  =  $\frac{1}{4}$  of this

=  $\frac{1}{4}$  X  $\frac{3}{2}$

=  $\frac{3}{8}$

∴  $\frac{3}{8}$  of an hour was spent on mathematics
