Question

do the ratios 22:30 and 7:12 form a proportion? yes no

Explanation:

Step1: Cross - multiply the ratios

For the ratios $a:b$ and $c:d$, we check if $a\times d=b\times c$. Here, $a = 22$, $b = 30$, $c = 7$, and $d = 12$. So we calculate $22\times12$ and $30\times7$.
$22\times12 = 264$ and $30\times7=210$.

Step2: Compare the products

Since $264
eq210$, the two ratios are not in proportion.

Answer:

no
