Sam cut a flat wooden board into fourths. He used three of the pieces as backgrounds for posters. He used equal pieces of the le
grandymaker [24]
To answer this question you would start with 1 whole piece and break it into 4 equal pieces. Each piece would be 1/4 of the original.

If you used 3 of these, you are left with 1/4.

Out of the 1/4 leftover, you create 5 equal-sized pieces.

1/4 divided by 5.
1/4 x 1/5 = 1/20 of the original board for each.

Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.

Harrison has 70 CDs in his music collection.
Eduardwww [97]

Answer:

14

Step-by-step explanation:

First, find the percentage of the other types of music.

Since 30 + 50 = 80, the other 20% will be other music.

To find 20% of 70, multiply 70 by 0.2:

70(0.2)

= 14

So, there are 14 CDs that are other types of music.
