A. before you can write an equation to solve the problem below, what must you do to 26%? 45 is 26% of what number? b. write an equation and solve. (show some work so i can understand what you did.)

Hello there! For this question, to find the number, we will write and solve a proportion. 

A. First off, 26% will go over 100%, because 26 is part of 100. This will be written as a fraction. It will be written as 26/100.

B. Okay. Let's write our proportion, it wil be written as 45/x = 26/100, because 45 is part of a number, and x represents the whole number. Let's start cross multiplying the fractions. 100 * 45 is 4,500. 26 * x is 26x. That leaves 4,500 = 26x. Now, divide each side by 26 to isolate the x. 26x/26 cancels out. 4,500/26 is 173.07692 and other numbers or 173 when rounded to the nearest whole number. There. 45 is approx. 26% of 173.

20 percentage, you can also do it on a calculator.
