Question

Пропорцыя5:2,5=20:16

Answer 1

5*16/20*2.5=80/50=8/5=1.6

Answer 2

To check whether the two ratios are equivalent, we can cross-multiply and see if the products are equal.

The given proportion is:

Proporcya 1: 5 Proporcya 2: 2.5

Now, let's check if the two ratios are equivalent:

Cross-multiplying: 1 * 2.5 = 2.5 5 * 1 = 5

So the two cross-multiplications give us:

Proporcya 1: 2.5 Proporcya 2: 5

Now, let's compare these results to the second ratio:

Proporcya 1: 20 Proporcya 2: 16

Since 2.5 is not equal to 20 and 5 is not equal to 16, the two ratios are not equivalent.

In conclusion, the statement "Proporcya 5:2,5=20:16" is not correct. The two ratios are not equal.
