Question

At the sewing store, Helen bought a bag of mixed buttons. The bag included 30 buttons, of which 20% were large. How many large buttons did Helen get?

Answer 1

6

Explanation:

Let's first look at the information the question gives us. Helen bought a bag with 30 buttons, 20% of which were large. That means, we have to find 20% of 30 to find out how many large buttons Helen bought.

Percentages can also be represented as fractions. Think of percentages as numbers out of 100. This means 20% can be represented as 20/100.

Now, all we need is to multiple 20/100 by 30 which gives us...

20/100 × 30 = (20 × 30)/100 = 600/100 = 6

Helen got 6 large buttons.
