Question

What fraction is to be subtracted from `9 3/7` to get `3 1/5`?

Answer 1

`9 3/7` − (The number to be subtracted) = `3 1/5`

∴ `9 3/7 - 3 1/5` = The number to be subtracted

∴ The number to be subtracted = `(9 + 3/7) - (3 + 1/5)`

= `(9 - 3) + (3/7 - 1/5)`

= `6 + (((3 xx 5) - (1 xx 7))/(7 xx 5))`

= `6 + ((15 - 7)/35)`

= `6 + 8/35`

∴ The fraction to be subtracted = `6 8/35`
