उत्तर
`17/2 + 3 1/2` = 12.
Explanation:
We have,
`17/2 + 3 1/2 = 17/2 + (3 xx 2 + 1)/2` ...`[((because "Mixed fraction" = "Improper fraction"),(= ("Whole number" xx "Denomiantor" + "Numerator")))/("Denominator")]`
= `17/2 + 7/2`
= `(17 + 7)/2`
= `24/2`
= `(24 ÷ 2)/(2 ÷ 2)` ...[∵ HCF of 24 and 2 is 2]
= 12
