Question

do the ratios 6:5 and 9:8 form a proportion?
yes
no

Explanation:

Step1: Cross - multiply the ratios

For ratios $a:b$ and $c:d$, check if $a\times d=b\times c$. Here, $a = 6$, $b = 5$, $c = 9$, $d = 8$. Calculate $6\times8$ and $5\times9$.
$6\times8=48$ and $5\times9 = 45$.

Step2: Compare the products

Since $48
eq45$, the cross - products are not equal.

Answer:

no
