Question

A girl completed her work in 3 days. On the first day she did 2/5 of the work and on the second day she did 3/7 of her work. How much work did she do on third day?​

Answer 1

Answer:

at first we add to 2/5 + 3/7

lcm of 5 , 7 is 35

then

multiply 2 / 5 from 7 both sides

multiply 3/7 from 5 both sides

then answer

14 / 35 + 15 / 35

29 / 35

then subtract 29 /35 from 3 / 1

3/ 1 - 29 / 35

lcm of 1 , 35 is 35

then

multiply 3/1 from 35 both sides

multiply 29 / 35 from 35 both sides

then answer

105 / 35 - 29 /35

then

8
