Answer:
5) 1/3=x/12
12=3x
3x=12 (divide both sides)
12 divided by 3 = 4
therefore, x = 4
6) 5/9=25/y (cross multiply the numbers)
after cross multiplying you should get: 5y=225
divide both sides to get 45
therefore, y = 45
7) 26/z = 13/22 (cross multiply numbers)
after cross multiplying, you should get: 572=13z (swap the numbers)
after swapping the number, you should get: 13z=572 (divide both sides)
after dividing you should get 44
therefore, z = 44
8) b/30 = 2.6/1.5 (simplify expression)
after simplifying you should get: b/30=26/15 (cross multiply after)
after cross multiplying you should get: 15b = 780 (divide both sides)
after dividing both sides, you should get: 52
therefore, b = 52
Hope this helps:)!
