Hi.
I need help with the following problem. Could someone rephrase this for me please.
5 = (is) , fifths = \frac{1}{5} but they ask how many thus, it becomes \frac{x}{5}, of 10 means (\times 10)
hence, re-writing in mathematical notation
5 = \frac{x}{5} \times 10 or x = 2.5
Some very good explanation in here : https://greprepclub.com/forum/5-is-how-many-fifths-of-3618.html

Got it. Thanks.
A fifth of 10 is 2.
So the question is asking this: By which number should we multiply 2 (the fifth of 10) to get a 5?
And the answer is 2.5.
