Answer:
- 42 students; (28 students); 70 students
- (60%); 40%; (100%)
Step-by-step explanation:
The percentages total 100%, so the missing percentage is
100% - 60% = 40%
The numbers on the number lines are proportional, so now you can write ...
?/100% = 28/40% . . . . . . ? total students
Multiplying by 100% gives ...
? = 28/0.4 = 70 . . . . . total students
Then the 60% portion of students can be found two ways:
60% × 70 = 42 students . . . . 60% of students
70 -28 = 42 students
Answer: 36 / 2 1/4
Step-by-step explanation:
From the question, we are informed that Jared needs to drill holes 2 1/4 inches apart in a 36 inch section of his garage. The expression that he can use to figure out the number of holes he will need to drill will be:
= 36 ÷ 2 1/4
From the expression we can then calculate the number of hours to drill. This will be:
= 36 / 2 1/4
= 36 / 9/4
= 36 × 4/9
= 16
He'll need to drill 16 holes
