What is 56 1/4 as a fraction in simplest form?

Luba_88 [7]

We have to simplify $56 \frac{1}{4}$ %

This is a mixed fraction, with 56 as the whole number part and $\frac{1}{4}$ as the fractional part

Such a fraction can be simplified as:

Denominator of simplified fraction = Denominator of mixed fraction

and Numerator of simplified fraction = (Denominator of mixed fraction × Whole number) + (Numerator of simplified fraction)

⇒ Denominator of simplified fraction = 4

and Numerator of simplified fraction = (4 × 56) + (1)

⇒ Numerator of simplified fraction = 225

Hence, the mixed fraction in its simplest form is $\frac{225}{4}$
