Answer ক. `0.3 = (3 - 0)/9`
` = 3/9`
` = 1/3`
`0.6 = (6 - 0)/9`
`= 6/9`
`= 2/3`
:. `0.3 -: 0.6 = 1/3 -: 2/3`
`= 1/3 xx 3/2`
`= 1/2 = 0.5`
:. নির্ণেয় ভাগফল = 0.5
খ. `0.35 = (35 - 3)/(90)`
`= (32)/(90)`
`= (16)/(45)`
`1.7 = (17 - 1)/9`
`= (16)/9`
:. `0.35 -: 1.7 = (16)/(45) -: (16)/(45) xx 9/(16)`
`= 1/5`
= 0.2
নির্ণেয় ভাগফল = 0.2
গ. `2.37 = (237 - 23)/(90)`
`= (214)/(90)`
`0.45 = (45 - 4)/(90)`
`= (41)/(90)`
:.` 2.37 -: 0.45 = (214)/(90) -: (41)/(90)`
`= (214)/(90) xx (90)/(41)`
`= (214)/(41)`
`= 5.2195121951`
`= 5.211951`
নির্ণেয় ভাগফল = 5.21951
ঘ. `1.185 = (1185 - 1)/(999)`
` = (1184)/(999)`
`0.24 = (24 - 0)/(99)`
` = (24)/(99)`
:. `1.185 -: 0.24 = (1184)/(999) -: (24)/(99)`
`= (1184)/(999) xx (99)/(24)`
`= (148)/(111) xx (11)/3`
`= (148 xx 11)/(111 xx 3)`
` = (1628)/(333)`
`= 4.888`
`= 4.8`
নির্ণেয় ভাগফল = 4.8
