<h2>a = 11 / 6</h2>
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
<em>When dividing fractions:</em>
<em>Convert 7 to a fraction: </em>
<em>Flip the second fraction and multiply.</em>

a = 77 / 42
Simplify the fraction by dividing be a common factor - 7.
77 ÷ 7 = 11
42 ÷ 7 = 6
<h2>a = 11 / 6</h2>
