Malory got a 75% on her math test. To earn that score, she got 27 questions correct. Write an equation to find how many questions were on the test. Then solve

75% = 0.75

Let y = amount of questions answered correctly.

Let x = total questions on the test.

y = 0.75x

In this problem,

y = ?

x = 27

Plug our numbers into the equation we made above.

27 = 0.75x

Divide both sides by 0.75

36 = x

There were 36 questions on the test.

the 4th choice is the correct one

step-by-step explanation:

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
