Question

What is the rate if the base is 244 and the portion 50

Answer 1

Step1:Write out the formula

`\frac{\text{portion}}{base}=\frac{rate\text{ }}{100}`

Step2; write out the parameters

`\begin{gathered} portion=50 \\ \text{Base}=244 \end{gathered}`

Step3: Substitute into the formula and simplify

`(50)/(244)=(rate)/(100)`

Step4: simplify the expression above

`\begin{gathered} \text{ Multiply both side by 244} \\ \text{rate}*244=100*50 \\ \text{then} \\ \text{ Rate=}(100*50)/(244) \end{gathered}`

Then the rate becomes

`20.49\text{ }`

Therefore the rate is 20.49
