Ms groves had trays of paint each tray has five colors one of the colors is purple.what fraction of the colors in 20 trays is purple

Answers

The correct answer is:
$(4)/(20) = (1)/(5)$ .

Explanation:
Since 1 out of 5 trays are purple, this means the fraction is $(1)/(5)$ .
However, to find the number of trays out of 20, we multiply 20 by $(1)/(5)$ :
20* $(1)/(5)$ = $(20)/(1) * (1)/(5) = (20)/(5) = 4$ .

Answer:

$(1)/(5)$

Step-by-step explanation:

Given : Ms groves had trays of paint each tray has five colors one of the colors is purple

To Find:. What fraction of the colors in 20 trays is purple

Solution:

Since each tray contains 5 colors

So, 20 tray contains no. of colors = 20*5

=100

Now we are also given that 1 out of five color is purple

So, each tray contain no. of purple color = 1

So, 20 tray contains purple color = 20*1 = 20

So, the fraction of the colors in 20 trays is purple :

$=\frac{\text{No. of purple colors in 20 trays}}{\text{Total No. of colors in 20 trays}}$

$=(20)/(100)$

$=(1)/(5)$

Thus the $(1)/(5)$ fraction of the colors in 20 trays is purple
