Answer 2

Answer:

The size, number, or amount of one thing or group as compared to the size, number, or amount of another. the proportion of boys to girls in our class is three to one.

If a,b,c and d are in proportion,then

a:b::c:d or a/b=c/a or a×d = b×c (b is not equal to 0,d is not equal to 0)

where a and d are called the extreme terms and b and c are called the middle terms.

So, the numbers a,b,c and d will be in proportion,if product of extreme terms = product of middle terms.
