Question

What is 12 1/2 X 4? I rlly need to know

Answer 1

SOLUTION

We want to solve

$12\frac{1}{2}\times4$

To do this, change the mixed fraction into improper fraction.

We say, 2 multiplied by 12, then plus 1. We write the result as the numerator over the denominator which is 2. That is

$\begin{gathered} 12\frac{1}{2}\text{ to improper fraction becomes } \\ 2\times12=24 \\ 24=1=25.\text{ this becomes } \\ \frac{25}{2} \end{gathered}$

We then multiply by 4, we have

$\begin{gathered} \frac{25}{2}\times4 \\ This\text{ becomes } \\ \frac{25}{2}\times\frac{4}{1} \\ 2\text{ cancels itself is 1, and into 4, it is 2. So we have } \\ \frac{25}{1}\times\frac{2}{1} \\ =\frac{25\times2}{1\times1} \\ =\frac{50}{1} \\ =50 \end{gathered}$

Hence the answer is 50
