Is the ratio 25 to 16 proportional to the ratio 5 to 4
1 answer:
To check you can set the ratios up as fractions, then cross multiply.
If they equal the same thing they are proportional, if they don't, they are not.
<u> 25</u> = <u>5</u>
16 4
Cross multiply (25)(4) = (16)(5)
100 = 80
Since 100 does NOT equal 80 the ratios are NOT proportional.
