One day at St. Philip's High School, 1/2 of the pupils walked to school, 1/5 of the pupils came to school by bus, and the remaining 57 pupils came by car.What fraction came to school by car?

Answers

Answer 1

Answer: The first thing to do is the make the denominators of the fractions the same.

5/10 of the pupils walked to school and 2/10 of the pupils came to school by bus.
5/10 + 2/10 = 7/10.
10/10 - 7/10 = 3/10.

3/10 of the pupils came to school by car.

If Walt can paint 25 feet of fence in an hour, and Joe can paint 35 feet in an hour, howmany minutes will it take them to paint a 150-foot fence, if they work together?

Answers

If Walt paints 25 ft. on one hour, and Joe pairs 35 ft in an hour, then they paint 60 ft per hour together. So, 60ft divided into the 150 ft fence equals 2 1/2 hours.

It will take Walt & Joe 2 1/2 hours to paint a 150ft fence.
