are the ratios 84/105 and 128/160 proportional?

give two different reasons to support your answer

The ratios 84/105 and 128/160 are proportional

Solution:

Given, two ratios are and

We have to give two different reasons to support the answer.

Reason 1:

Now, we know that, numerators and denominators should be proportional to be two fractions in proportion.

So numerators and denominators are in proportion, then given two fractions are proportion.

Reason 2:

Now, values of two fractions must be equal:

So, values of two fractions are equal, then they are in proportion.

Hence, the given two fractions are in proportion.

i think it is 18

step-by-step explanation:

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
