Question

do the ratios 1:2 and 2:3 form a proportion?
yes
no

Explanation:

Step1: Write ratios as fractions

The ratio $1:2$ is $\frac{1}{2}$, and the ratio $2:3$ is $\frac{2}{3}$.

Step2: Check for equality

We need to check if $\frac{1}{2}=\frac{2}{3}$. Cross - multiply: $1\times3 = 3$ and $2\times2=4$. Since $3
eq4$, $\frac{1}{2}
eq\frac{2}{3}$.

Answer:

no
