Answer:
71%
Step-by-step explanation:
I think the easiest way to think of this is to pretend that there are a total of 100 students at the high school, so that means the amount of people who work part time is 45% of 100 = 45 people. If 60% of those students love math, you do 0.6 * 45 = 27 people.
Next, 80% of the students who do not have a part time job (100 - 45 = 55) love math, so 0.8 * 55 = 44 people.
44 + 27 = 71, so the percent is 71/100 = 71%.
let me know if any part of that doesn't make sense
Answer:
<u>1/6</u>
Step-by-step explanation:
<u>P (red)</u>
- No. of red / Total
- 3 / 3 + 4 + 2
- 3/9
- 1/3
<u>P (green without replacing red)</u>
- No. of green / Total - 1
- 4 / 9 - 1
- 4/8
- 1/2
<u>P (final)</u>
- P (red) × P (green without replacing red)
- 1/3 × 1/2
- <u>1/6</u>
30%
This is because it is 3/10
The 10 is 100%
He drank 3/10 of it
Divide 100 by 3
You get 30
Your answer is 30%
