व्‍यंजक `(3 1/4-4/5 "of" 5/6)/(4 1/3-:1/5-(3/10+21 1/5))` में से वह कौन सा भिन्न घटाया जाए कि परिणाम एक पूर्णांक हो?

Options

A. `1/2`
B. `5/6`
C. `1/4`
D. `3/10`

Answer

A

Explanation

According to the question
`implies(3 1/4 -4/5 "of 5/6)/(4 1/3 -: -(3/10+21 1/5))`
`implies (13/4-4/5xx5/6)/(13/3xx5-(3/10+106/5))`
`implies (13/4-2/3)/(65/3-3/10-106/5)implies((39-8)/12)/((650-9-636)/30)`
`implies 31/12xx30/5=31/2=15 1/2`
`:.` Least fractiion number
should be subtracted is `15 1/2-15=1/2` (least fraction number)
