The ratio of Lauren's Age to Kristen's Age =
Ratio of two numbers is a quantitative relationship between two numbers showing that how one number is increasing or decreasing with respect to other number.
If a and b are two numbers then the their ratio r is represented by the equation (1)
Lauren' s Age =
Kristien's Age =
For Finding out the ratio of two numbers we simply divide them.
Let x be the ratio of Lauren's age to Kristen's age, = x = /.....(2)
On simplifying equation (2) we get
x =
So the ratio of Lauren's Age to Kristen's Age =
