Question

Jason downloaded 288 pictures from his camera. Of the pictures, 38% are of his family. About how many pictures are of his family? Use a rate per 100 to estimate.

Answer 1

We can rewrite this problem as:What is 38% of 288?

"Percent" or "%" means "out of 100" or "per 100", Therefore 38% can be written as

38 /100

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number of pictures we are looking for "p".

Putting this altogether we can write this equation and solve for p while keeping the equation balanced:

p = 38 /100 × 288

p = 10944 /100

p = 109
