If you write a fraction that is equivalent to 3/5 but has denominator 30, my number will be the sum of the numerator and the denominator of this fraction. What is my number?

Given:

The fraction is .

Denominator of equivalent fraction is 30.

To find:

The sum of numerator and the denominator of this fraction.

Solution:

We have,

To make denominator 30 multiply the numerator and denominator by 6.

Now, add numerator add denominator.

Therefore, the required number is 48.

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
