Question

What should be subtracted from the product of 3/7 &1/5 to get 4/35?

Answer 1

Product of 3/7 and 1/5 = 3/7*1/5

                                     = 3/35

Let the subtracted number be x

-> 3/35 - x = 4/35

-> 3/35 - 4/35 = x

-> -1/35 = x

Hope you understood properly :D

Answer:

-1/35

(3/7) *(1/5) -x=4/35

x= -1/35
