Question

2/5 - 2/7Write your answer as a fraction in simplest form.

Answer 1

To do subtraction in fractions, we need to equal the number in the denominator. Due that 5 and 7 don't have any number in common, we need to multiply 5 x 7= 35. Then, we multiply the numerator of the fraction with the number that was multiplied in the denominator. Let's see:

`\begin{gathered} (2)/(5)\text{ - }(2)/(7)= \\ (2(7))/(35)\text{ - }(2(5))/(35)= \\ \frac{14\text{ -10}}{35}= \\ (10)/(35)=\text{ No we can simplify the fraction dividing both numbers by 5. } \\ \\ (2)/(7) \\ \\ The\text{ answer is }(2)/(7) \end{gathered}`
