Studdy Solution

STEP 1

Assumptions1. The total number of babies born is35. . The number of boys born is27.
3. We are asked to find the percentage of boys among the newborns.

STEP 2

To find the percentage of boys, we need to divide the number of boys by the total number of babies, and then multiply the result by100.
Percentage of boys=(Number of boysTotal number of babies)times100%Percentage\, of\, boys = \left(\frac{Number\, of\, boys}{Total\, number\, of\, babies}\right) \\times100\%

STEP 3

Now, plug in the given values for the number of boys and the total number of babies to calculate the percentage.
Percentage of boys=(2735)times100%Percentage\, of\, boys = \left(\frac{27}{35}\right) \\times100\%

STEP 4

Perform the division operation.
Percentage of boys=0.7714285714285714times100%Percentage\, of\, boys =0.7714285714285714 \\times100\%

STEP 5

Multiply the result by100 to get the percentage.
Percentage of boys=77.14285714285714%Percentage\, of\, boys =77.14285714285714\%

STEP 6
