Charlie, a science teacher, worked 10 months out of the year. What percent of the year did he work? A. 0.12% B. 12% C. 83.3% D. 93.6%
Lets see. There are 12 months in a year. He worked 10 months. We know that if we have 10 months, Than 1 month is 10% of 10 months And 8 months is 80% of 10 months. So, based on the afore information, what do you think 10 months out of 12 will be?
There is also a scientific method to doing this. Take the fraction, say, 12/10, and divide it by itself.
\[\frac{ 10 }{ 12 }=\frac{ x }{ 100 }\] Cross multiply to get 12x=1000 Divide by 12 on both sides and you get x=83.3
its c use cross multiplication to solve
