There are 15 pieces of fruit in a bowl and 6 of them are apples. What percentage of the pieces of fruit in the bowl are apples?

zavuch27 [327]

Answer:

40%

Step-by-step explanation:

Total amount is 15

6 out of the 15 amount are apples

Thus, 6/15 x 100 = 40%

You could ask yourself, what number do I multiply by 15 to get to 100?

Then, multiply the top (numerator) by it.

The value of the numerator will give you the final % (percentage) due to percentage being out of 100.

Hope this helps!
