Question

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

Answer 1

We want to solve

`12(1)/(2)*4`

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(1)/(2)\text{ to improper fraction becomes } \\ 2*12=24 \\ 24=1=25.\text{ this becomes } \\ (25)/(2) \end{gathered}`

We then multiply by 4, we have

`\begin{gathered} (25)/(2)*4 \\ This\text{ becomes } \\ (25)/(2)*(4)/(1) \\ 2\text{ cancels itself is 1, and into 4, it is 2. So we have } \\ (25)/(1)*(2)/(1) \\ =(25*2)/(1*1) \\ =(50)/(1) \\ =50 \end{gathered}`

Hence the answer is 50
