1) To solve for x in the equation 8/9 = 3/42, we can cross multiply to get:
8 42 = 9 3336 = 27x = 336/27x = 12.44
2) To solve for x in the equation x/2.8 = 5/7, we can cross multiply to get:
x 7 = 2.8 57x = 14x = 14/7x = 2
1) To solve for x in the equation 8/9 = 3/42, we can cross multiply to get:
8 42 = 9 3
336 = 27
x = 336/27
x = 12.44
2) To solve for x in the equation x/2.8 = 5/7, we can cross multiply to get:
x 7 = 2.8 5
7x = 14
x = 14/7
x = 2
