Question

Hi I need to subtract two fractions or improper fractions I’m not sure I need to subtract 9/14 -3/7

Answer 1

In order to calculate this subtraction, first we need to put both fractions in the same denominator.

To do so, we need to find the least common multiple (LCM) between 14 and 7.

Since 14 is a multiple of 7, the LCM between 14 and 7 is 14.

So we can calculate the subtraction by doing the following steps:

`\begin{gathered} (9)/(14)-(3)/(7)\\ \\ =(9)/(14)-(3)/(7)\cdot(2)/(2)\\ \\ =(9)/(14)-(6)/(14)\\ \\ =(9-6)/(14)\\ \\ =(3)/(14) \end{gathered}`

Therefore the result is 3/14.
