→ The way I like to do these kind of math problems is below - I find it easier
A fraction usually means to divide, so I will start by dividing the numerator by the denominator of 7/10.
7/10 = 0.7, or, 70%
1/5 = 0.2, or, 20%
Now, we can go and divide each of our answers together.
0.7 ÷ 0.2 = 3.5 :D
Your final answer is 3.5
