Lee was looking at 21 different colors to paint her bedroom. She liked about 3/5 of the colors. About how many colors did she like (Round to the nearest whole number)

The number of colors she did like is 13.

Step-by-step explanation:

Lee was looking at 21 different colors to paint her bedroom.

The total number of colors = 21

She liked about 3/5 of the colors.

Let, the number of colors she liked = x

We know that, x is 3/5 colors of 21 different colors.

Therefore, the equation is framed as x = (3/5) × 21

To find the number of colors she liked :

Solve the framed equation for x value,

⇒ x = 3 × 4.2

⇒ x = 12.6

In order to round the x value to the nearest whole number, check whether the number after the decimal point is greater or less than 5.

If the number after the decimal is greater than 5, then add 1 to whole number.

Here, we have 6 after the decimal point which is greater than 5.

So, x = 13.

∴ The number of colors she did like is 13.

5x+10 is the correct one

hope this
