Question
`2(1/3)` + `4(1/4)` + `4(2/3)` +
`8(7/6)` + ? = `4(3/5)xx4(1/2)` What will come in the place of question mark (?) in the following given question:Solution
`2(1/3)` + `4(1/4)` + `4(2/3)` + `8(7/6)` + ? = `4(3/5)xx4(1/2)` (2 + 4 + 4 + 8) [`(1/3)` + `(1/4)` + `(2/3)` + `(7/6)` ] + ? = `207/10` `20(5/12)` + ? = `207/10` ? = `(207/10)` - `(245/12)` ? = `17/60`
