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 $\frac{225}{4}$

Find the vector, not with determinants, but by using properties of cross products. k × (i − 3j)

sergey [27]

$\mathbf k\times(\mathbf i-3\mathbf j)=(\mathbf k\times\mathbf i)-3(\mathbf k\times\mathbf j)$
$=\mathbf j-3(-\mathbf i)$
$=3\mathbf i+\mathbf j$

A percent is a fraction whose denominator is 100. Always Sometimes Never

madreJ [45]

It's sometimes, because let's say I have 4/5 right? So when in a percent it's 80%. I suppose you could turn it into a a decimal of 80/100 but no not always. 3295729357/1000000000000. That doesn't have a denominator of 100, so yeah.
