For homework, brooke has 15 math problems, 5 social studies problems, and 9 science problems. use mental math to determine how many problems she has for homework. tell which property you used.

29 problems

Step-by-step explanation:

Brooke has some problems for her homework.

Math problem = 15

Social studies problem = 5

Science problem = 9

We will add all the problems to get the total number of problems.

She has total problems for her homework = 15 + 5 + 9

                                                                      = 29 problems

We used addition to solve this question.

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
