Question

What number is 45% of 180

Answer 1

This written statement can be converted into an equation. 
**What number** can be "x" (unknown value being solved for). 
**is** is the equal sign (=) 
**45%** can be transferred to decimal form, "0.45"
**of** is the key word to multiply, so "times"
**180** can remain 180. 
We now have this equation: 
x = 0.45 x 180
x = 81
81 is 45% of 180.
