mike withdrawed money from the bank he spent a fourth of it on gas and has $90 left. how much money did he withdraw? Jun 16, 2017 ### 3+0 Answers #1 +7347 +3 Let's call the amount of money he withdrawed " m " . m - ( $$\frac14$$ )m = 90 Factor out an m on the left side. m( 1 - $$\frac14$$ ) = 90 m($$\frac44-\frac14$$) = 90 m($$\frac34$$) = 90 Multiply both sides of the equation by $$\frac43$$ m = 90 * $$\frac43$$ m = 120 Jun 16, 2017 #2 +95175 +2 If he spent a 1/4 then he must have 3/4 left So$90   is   3/4     of the original amount

If you divide that by 3 you will have 1/4 of the original amount so

90 / 3   =  $30$30 is   1/4   of the original amount.

If you multiply that by 4 you will have the orriginal amount.

$30 * 4 =$120
