Question

If one third of a number is substrates from twice the number the result is 55. What is the number. ?

Answer 1

Let the number be x:

So intepreting the word problem into words we will have:

`2x-(1)/(3)x=55`

Simplifying further, we will have:

`\begin{gathered} (5)/(3)x=55 \\ \end{gathered}`

Cross multiply:

`\begin{gathered} 5x=165 \\ x=(165)/(5) \\ x=33 \\ \text{The number is 33} \end{gathered}`
