a = 11 / 6
You want to find out what a is.
7a / 10 = 77 / 60
Put your equation into the form Ax = B, where x = a
You can multiply both sides by 10 to get rid of the denominator.
7a / 10 * 10 = 77 / 60 * 10
7a = 77 / 6
Put your equation into the form x = B, where x = a
You can get a on it's own by dividing both sides by 7.
7a ÷ 7 = 77 / 6 ÷ 7
a = 77 / 6 ÷ 7
