Question 599536
34 baby boys make up 54% of the babies born.



So if x is the total number of babies, then


Percent/100 = Part/Whole


54/100 = 34/x


Now solve for x


54/100 = 34/x


54x = 34*100


54x = 3400


x = 3400/54


x = 62.96296


Round this value to the nearest whole number (since you can't have a fraction of a person) to get x = 63



So there are 63 babies total.


Now let y = number of girls born. This means that y baby girls make up 46% of the babies born (since 54% + 46% = 100% or 100 - 54 = 46)



Therefore, we can say that


Percent/100 = Part/Whole


46/100 = y/63



Now solve for y



46/100 = y/63


46*63 = 100y


2898 = 100y


2898/100 = y


28.98 = y


y = 28.98


Round this to the nearest whole number (you can't have a fractional amount of girls) to get y = 29



So 29 girls were born over the past week.
