`9 1/4 - 5/4` = ______.
उत्तर
`9 1/4 - 5/4` = 8.
Explanation:
We have, `9 1/4 - 5/4 = (9 xx 4 + 1)/4 - 5/4` .....`[(because "Mixed fraction" = "Improper fraction"),(=(("Whole number x Denomiantor + Numerator"))/"Denominator")]`
= `37/4 - 5/4`
= `(37 - 5)/4 = 32/4`
= `(32 ÷ 4)/(4 ÷ 4)` .....[∵ HCF of 32 and denominator 4 is 4]
= 8
