Question:If `617 ÷ 24.68 + x = 90`,find the value of `x`.
Let, `617 ÷ 24.68 + x = 90`. Then, `617/24.68 + x = 90` or `25 + x = 90` or `x = (90 - 25)` `= 65`
Question:`1 +1/` `1 + 1/` `1 + 1/5`
Given Expression ,
`1 + 1/`
`1 + 1/((6/5))`
`= 1 + 1/`
`= 1 +5/6`
`= 1 + 1/(11/6)`
`= (1 + 6)/(11)`
`= 16/11`.Question:`1 - 5/` `7 + 1` `4 + 1` `2 + 1/3`
Given Expression ,
`= 1 - 5/`
`7 + 1/`
`4 + 1/(7/3)`
`= 1 - 5/`
`7 + 1/4 + ( 3/7)`
`= 1 - 5/`
` 7 + 1/(31/7)`
`= 1 - 5/`
`7 + 7/(31)`
`= 1 - 5/(224/31)`
`= (1 - (5 xx 31)/(224))`
`= ((224 -155)/(224))`
`= (69)/(224)`Question:A boy was asked to multiplied a certain number by `53`.He multiplied it by `35` and got his answar less than the correct one by `1206`.Find the number to be multiplied
Let the required number be x.Then, `53x -35x` `= 1206` or `18x` `= 1206` or `x = 67` :. Required number `= 67`.
