Question:`2 - [3 - {6 - { (5 - bar4 - 3) } ]`
Given Expression ,
` = 2 - [3 - { 6 - (5 - 1) } ]`
`= 2 - [3 - {6 - 4} ]`
`= [3 - 2]`
`= (2 - 1)`
`= 1`.Question:`[3 1/4 ÷ {1 1/4 - 1/2 (2 1/2 - bar1/4 - 1/6)}]`
`[13/4 ÷ { 5/4 - 1/2 (5/2 - (3-2)/12)}]`
`= [13/4 ÷ { 5/4 - 1/2 (5/2 - 1/12)}]`
`= [ 13/4 ÷ { 5/4 - 1/2 ((30 - 1)/12)}]`
`= [ 13/4 ÷ { 5/4 - 29/24}]`
`= [ 13/4 ÷ { (30 - 29)/24}]`
`= [ 13/4 ÷ 1/24]`
`= [ 13 xx 24]`
`= 78`.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)`
