6 is 40% of a number. Which step explains how to find the number?

Question

please solve this as soon as you can

 

Answer 1

Another way is to set up a proportion.  We know that a percent is a number out of 100.  40% is 40 out of 100.

 

 

6 / x = 40 / 100

 

where x = the number that we want to find.

 

 

Cross multiply from the proportion.

 

40x = 600

 

 

Divide both sides of the equation by 40.

 

x = 15

 

 

This means that 6 is 40% of 15.

 

 

Answer 2

6   is   40%    of      a number

6   =   0.4      ·          n

 

6 = 0.4n                divide both sides by 0.4.

15 = n

 

Check:

 

6 = 0.4(15)

6 = 6
