A photocopier can print 116 copies every 4 minutes. How many copies can it print in 1.25 hours?
1 hour = 60 minutes
.25 hour = 15 minutes
60 + 15 = 75 minutes
Per minute: 116 ÷ 4 = 29
29 × 75 = 2,175
60 minutes in an hour, so 1.25 hours = 75 minutes
116 copies in 4 minutes means 29 copies per minute
so, what do you think?
how many dictionaries can be made in 10 minutes

Anonymous, I think that it's 29 × 75.
It's 2175. Do you think that I used a calculator?
116Copies/4min. * 60min/h * 1.25h = 2175 Copies.
nah, multiply 30 by 75 in your head and subtract 75.
2250 - 75 = 2175
