Question

how to see if numbers are in proportion or not numbers are in proportion or not

Answer 1

Answer:

If, four numbers a, b, c and d as a:b::c:d .

Then, the first and last terms, a and d are called as extremes.

The two middle terms, b and c are called as means.

To prove, that the numbers are in proportion,

we have to multiply the extremes, i.e.,a*d,

and also multiply the means, i.e.,b*c.

If,

Product of extremes = Product of means

Then, the numbers are in proportion.

Answer 2

Answer:

Step-by-step explanation:

Let's take the number as a,b,c,d

Now a and d, i.e. first term and last term

And

b and c, i.e. second and third term.

If the ratios are equal to each other by simplifying then both of them are inproportion.
