Alonzo finished his inglish assignment in 1/2 hours.Then he completed his chemistry assignment in 3/5 hours.How much more time did Alonzo spend on his chemistry assignment?
It took him 6 minutes longer to complete chemistry assignment or 1/10 hours more. We can calculate this simply by subtracting 1/2 out of 3/5 : 3/5-1/2=1/10
