What is 15% of 60?? Can someone plz tell me how to calculate this as well??? Thanks!!!

earnstyle [38]

To convert a percentage to a decimal you move the decimal two places to the left. Therefore:

15.% becomes .15

You then multiply this decimal to the number you are trying to find the percentage of.

.15 × 60 = 9.

9 is 15% of 60.

The width of a rectangular room is 60% of its length. The length of the room is 10 feet. What is the area of the room?

SOVA2 [1]

Answer:

$60\ ft^{2}$

Step-by-step explanation:

Let

x-------> the length of the room

y-------> the width of the room

we know that

$60\%=\frac{60}{100}=0.60$

$x=10\ ft$

$y=0.60x$

Find the value of y

$y=0.60(10)=6\ ft$

The area of the rectangular room is equal to

$A=xy$

substitute the values of x and y

$A=10*6=60\ ft^{2}$
