Ratio of two number is what???
OpenStudy (anonymous):
Is it 3:7??
OpenStudy (anonymous):
Let the one number be: 3x So, other will be : 7x 7x + 4 = 3(3x - 4) 7x + 4 = 9x - 12 2x = 16 Find x from here.. And then find the numbers that are 3x and 7x..
OpenStudy (anonymous):
sorry that's 3: 7 typo
OpenStudy (anonymous):
2x = 16 Divide by 2 both the sides and get x.. Then find 3x and 7x..
