Respuesta :

texaschic101
22/88 = 10/40
cross multiply
(22)(40) = (88)(10)
880 = 880.....true proportion

2/12 = 6/24
(2)(24) = (12)(6)
48 = 72 (incorrect)....not a true proportion

7/x = 35/125
35x = 7(125)
35x = 875
x = 875/35
x = 25

2/6 = x/48
6x = 48(2)
6x = 96
x = 16 qt.

45% of 180...turn percent to fraction...." of " means multiply
0.45(80) = 36....so 45% of 180 is 36
