Question

4/11 and 10/27.5 do these ratios form a proportion?yes or no?

Answer 1

Yes, they form a proportion

Step-by-step explanation

A proportion is a statement that two ratios are equal.

We have to check if the next equality is true:

`(4)/(11)=(10)/(27.5)`

Instead of doing the divisions, we can do multiplications:

`\begin{gathered} 4*27.5=10*11 \\ 110=110\text{ }\rightarrow\text{ true} \end{gathered}`

These ratios are equal, so they form a proportion
