well I will do the last one
22/55 = 12/h
multiply both sides by the LCD which is 55 h
then
(22/55) (55 h ) = (12/h)(55 h)
or
22 h = 12 * 55
divide both sides by 11
2 h = 12 * 5
divide both sides by 2
h = 6 * 5
h = 30
-------------------
I have gone step by step to show you why.
You can just cross multiply which is the same thing in short hand:
22/55 = 12/h
is
22 h = 55 * 12
h = (55/22)*12 = (5/2)12 = 30
Solve each problem.
1.
two-thirds equals twelve over x
x = 18
x = 12
x = 36
x = 8
2.
six-elevenths equals eighty-four over x
x = 40
x = 120
x = 254
x = 154
3.
twenty-two miles over fifty-five hours equals twelve miles over h hours
48
30

Thanks can you check the other ones? Is 1 A and 2 D?
1 A yes
2.yes
6/11 = 84/x
6 x = 11 * 84
x = 11*14 = 154
2.yes
6/11 = 84/x
6 x = 11 * 84
x = 11*14 = 154
Thx
