Maria needs to make a total of 80 deliveries this week. So far she has completed 48 of them. What percentage of her total delive
Amiraneli [1.4K]

What I always do to solve this, is find a common factor for each number first.

Usually 4 or 5 works best. I'll use 4.

4 goes into 80 20 times, which means that 4 = 5%  of 80.

If 4 = 5%, and 48 = 12 x 4,    then 48 must equal 60% of 80.

(Another way to solve this problem is:  simplify 48 / 80.  This simplifies to 3/5.

3/5 = 60%)!
