The label needs to be a rectangle where the length is 4 times the width.

There are 18 pieces of chalk. The ratio of chalk that is yellow to chalk that is not yellow is 1:2. How many pieces of chalk are
vovangra [49]

Number of pieces of chalk that are yellow is 6

<h3><u>Solution:</u></h3>

Given that there are 18 pieces of chalk

To find: number of pieces of chalk that are yellow

Given that,  ratio of chalk that is yellow to chalk that is not yellow is 1 : 2

Therefore,

chalk that is yellow : chalk that is not yellow = 1 : 2

Let the chalk that is yellow be 1x

Let the chalk that is not yellow be 2x

Also, total pieces of chalk = 18

That is,

chalk that is yellow + chalk that is not yellow = 18

1x + 2x = 18

3x = 18

x = 6

number of pieces of chalk that are yellow = 1x = 1(6) = 6

Thus 6 chalk pieces are yellow
