Question

step by step ​

Answer 1

$\huge\mathfrak{\bf{\underline{\underline{\blue{Answer \ :}}}}}$

$\frac{20}{25} = \frac{80}{100} \\ \frac{4}{5} = \frac{4}{5}$

Therefore, They Are In Proportion

Answer 2

Answer:

No they are not in proportion

Step-by-step explanation:

Is 22:25::80:100

We know the product of extremes = product of means, so

Is 22x100 = 25x80

22x100 = 2200

25x80 = 2000

2200 ≠ 2000

So they are not in proportion.
