At birth, the ratio of a baby’s head length to the length of the rest of the body is 1:3. If a baby’s total body length is 22 inches, how long is the baby’s head?

Answers

The length of the baby’s head is 5.5 inches if the ratio of a baby’s head length to the length of the rest of the body is 1:3.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

It is given that:

At birth, the ratio of a baby’s head length to the length of the rest of the body is 1:3.

A baby’s total body length is 22 inches,

Let x be the head length

Let 3x be the

x + 3x = 22

4x = 22

x = 22/4 = 11/2 = 5.5 inches

Thus, the length of the baby’s head is 5.5 inches if the ratio of a baby’s head length to the length of the rest of the body is 1:3.
