20/4 means 5 * 4 = 20
2725/5 means 545*5 = 2725
0/5 = 0
==============
25x = 1475
x = 1475/25
x = 59 <== 59 boxes of diapers were bought
==============
18h + 70(36) = 4608
18h + 2520 = 4608
18h = 4608 - 2520
18h = 2088
h = 2088/18
h = 116....she did 116 haircuts
=================
575 + 13(118) = total cost Inverse operations to check...
575 + 1534 = total cost 2109 - 1534 = 575
2109 = total cost 575 = 575 (correct)
=================
320/39 = 2240/x....320 miles to $ 39 = 2240 miles to $ x
cross multiply
(320)(x) = (39)(2240)
320x = 87360
87360/320 = x
273 = x....it would cost $ 273
inverse operations to check....320 * 273 = 87360
87360 = 87360 (correct)
