3x - 7 + 6 = 7x + 6
First shift all the pure numbers to one side
3x = 7x + 6 + 7 - 6
Now add up the pure numbers
3x = 7x + 7
Shift the 7x to the other side
3x - 7x = 7
-4x = 7
Divide 7 by - 4
X = - 1.75
To convert from a fraction to a percent,
You just need to divide the fractions then multiply the product by 100.
Examples:
1. What is 3/4 in percent?
a. 3/4 = 0.75 x 100 = 75%
b. 45/98 = 0.46 x 100 = 46&
c. 60/100 = 0.6 x 100 = 60%
d. 1/5 = 0.2 x 100 = 20&
e. 6/99 = 0.06 x 100 = 6%
The answer is c.
