Question

Sum of two rational numbers is 3/5. if one of them is -2/7 find the other

Answer 1

Answer:

the answer is 31/35

Step-by-step explanation:

-2/7+x=3/5

x=3/5-(-2/7)

x=3/5+2/7

Now we will make the denominators equal to add them

3/5*7/7=21/35,   2/7*5/5=10/35

21/35+10/35=31/35

Now if we add them then we will have to convert -2/7 so

-2/7*5/5=-10/35 and if we add them the answer is -10/35+31/35=21/35

If we further simplify and convert 21/35 into it's simpler form we get 3/5 and that's the end result

Hope this makes it clear
