there are 80 fourth graders in school of these, 35 were boys. what fractional part of the fourth graders were girls

to get the fractional part of girls, we first subtract 35 from 80 to get the number of girls:

80 - 35 = 45
then we divide this by the total, which is 80:
45/80
reduce to lowest term by dividing both numerator and denominator by the GCF (greatest common factor) which is 5:
45/5 = 9
80/5 = 16
thus 45/80 = 9/16

hope this helps~ :)

To find the fractional part of fourth graders who were girls, we need to subtract the number of boys from the total number of fourth graders and express it as a fraction.

Total number of fourth graders = 80
Number of boys = 35

Number of girls = Total number of fourth graders - Number of boys
Number of girls = 80 - 35 = 45

Fractional part of fourth graders who were girls = Number of girls / Total number of fourth graders

Fractional part of fourth graders who were girls = 45 / 80

Simplifying the fraction, we get:

Fractional part of fourth graders who were girls = 9 / 16

Therefore, the fractional part of the fourth graders who were girls is 9/16.

To find the fractional part of fourth graders who were girls, we need to subtract the number of boys from the total number of fourth graders and then express it as a fraction.

Total number of fourth graders: 80
Number of boys: 35

To find the number of girls, we subtract the number of boys from the total number of fourth graders:

Number of girls = Total number of fourth graders - Number of boys
Number of girls = 80 - 35
Number of girls = 45

So, there were 45 girls in the fourth grade.

Now, to express this as a fraction, we can write:

Fractional part of fourth graders who were girls = Number of girls / Total number of fourth graders

Fractional part of fourth graders who were girls = 45 / 80

This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 5:

Fractional part of fourth graders who were girls = (45 ÷ 5) / (80 ÷ 5)
Fractional part of fourth graders who were girls = 9 / 16

Therefore, the fractional part of the fourth graders who were girls is 9/16.
