To solve each of these proportions, we will cross multiply and then solve for the variable.
457 = 63x315 = 63xx = 315/63x = 5
5x = 45x = 45/5x = 9
7x = 49*57x = 245x = 245/7x = 35
Therefore, the solutions to the proportions are:
To solve each of these proportions, we will cross multiply and then solve for the variable.
45:63 = x:7457 = 63x
5*x = 84-39315 = 63x
x = 315/63
x = 5
5x = 45
x:5 = 49:7x = 45/5
x = 9
7x = 49*5
7x = 245
x = 245/7
x = 35
Therefore, the solutions to the proportions are:
x = 5x = 9x = 35
