Question

1/5 + 3/7 my paper says add, write your answer in simplest form and u have to work it out ehat do i do?

Answer 1

`(22)/(35)`

Explanation:

The question above is answered below.

`(1)/(5) + (3)/(7)`

Take the LCM of the denominators and simplify. LCM is 5 × 7 = 35. Thus,

35/5 = 7; 7×1 =7. 35/7=5; 5×3=15. Hence the fraction below:

`= (7 + 15)/(35)`

`= (22)/(35)`

Note that the answer above cannot be expressed in simplest form because there is no common factor that divides 22 and 35 at the same time so we leave the answer in that form, as stated above.
