Hello guys..plz help me...its urgent...."explain the properties of ratio"here's the question ​

Answer»

• If a:B = c:d is a PROPORTION, then

• Product of extremes = product of means i.e., ad = bc

• a, b, c, d,…. are in CONTINUED proportion means, a:b = b:c = c:d

• a:b = b:c then b is called MEAN proportional and b2 = ac

• The third proportional of two NUMBERS, a and b, is c, such that, a:b = b:c

• d is fourth proportional to numbers a, b, c if a:b = c:d
