3/4 ÷ 3/4
step-by-step explanation:
basically divide any proper fraction with itself to fit the criteria.
so if we are using 3/4, then:
3/4 ÷ 3/4 = 1
so 1 is the quotient.
and the numerators for both these fractions is 3. and if we divide the numerators:
3 ÷ 3 = 1
we see that quotient is equal to our original quotient as well.
percentage - 25%
probability - 0.25
we know,
total amount of students in class = 20
total boys = 10
total girls = 10
no of girls who wear glasses = 10/2 = 5
probability of choosing a girl with glasses is =
number of girls wearing glasses/total number of students in the class = 5/20
thus, percentage of selecting a girl wearing glasses will be
= 5/20 × 100
= 5 × 5
25%
therefore,
probability will be 0.25
