Answer this problem

2  1/4

Step-by-step explanation:

1 3/4 + 1/2 =

Get a common denominator of 4     1/2 *2/2 = 2/4

1 3/4 + 2/4

1 5/4

We need to change the improper fraction to a mixed number

1+  4/4 + 1/4

1 + 1 + 1/4

2  1/4

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
