Grace spent 15 minutes on her math homework. That was 30% of the total number of minutes she spent doing homework. How many minutes did she spend doing homework?

Relax

Respuesta :

50 minutes

given 30% we require to find 100%

divide 15 minutes by 30 to obtain 1% and multiply by 100 for 100%

time = 15 × [tex]\frac{100}{30}[/tex] = 50 minutes
