∙ 16y agoBy 80 of a number, I presume you mean 80%. If so, set up the equation this way, with x representing the unknown number and .8x representing 80% of the number: x + ,8x = 252 and rewrite as 1.8x = 252; next step: divide both sides of the equation by 1.8 to find the value of x so the equation will look like this 1.8x / 1.8 = 252 / 1,8 and rewrite as x = 140. To prove the solution, substitute 140 for x and solve: 140 + 112 (80% of 140 is 112) = 252
