Tom had 7/12 of a pizza. His little sister came along and took 2/5 of his pizza away. How much pizza does Tom have left?

Answers

To find the answer,we can first calculate how much her sister took away by multiplying the original amount he has to the amount her sister took.

Her sister has:
7/12×2/5
=7/30

We can then find the amount of pizza left by deducting the pizza he has to the answer we found above:

7/12-7/30
=35/60- 14/60
=21/60
=7/20

Therefore he has 7/20 of a pizza left.

An alternative way to find the answer:
7/12×(1-2/5)
=7/12×3/5
=7/20

Hope it helps!

Carlos has 30 yards of plastic fencing to set up for a track meet he uses 85 feet of fencing how much fencing does he have left

Answers

There's 90 feet in 30 yards so 90 - 85 is 5
The first thing you need to know is that 1 yard = 3 feet. Therefore if he had 30 yards he had 90 feet of plastic fencing. From there all you have to do is take the 90 feet he has and subtract 85 feet he uses. That means Carlos has 5 feet of fencing left.
