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.
<h3>What is the ratio?</h3>
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.
