Not sure please help me?

Answer 1

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

Answer 2

Thanks can you check the other ones? Is 1 A and 2 D?

Answer 3

1 A yes

2.yes

6/11 = 84/x
6 x = 11 * 84
x = 11*14 = 154
