get a common denominator of 24
2/3 * 8/8 vs 7/8 * 3/3
16/24 vs 21/24
16/24<21/24
2/3 <7/8

First you have to remember that to find a percentage you can multiply a number by the percentage's decimal form, for example 40% of 100 would be .40 * 100.
Anyways, 24*.40 =9.6.
To find the percentage however, you must divide 24/40 which equals 0.6, which is equal to the percentage 60%.
To find the third question, you must multiply 24 by 2.5 (0.4 * 2.5 = 1) and you should get 60.
The last question you may have made a typo on, you repeated the first question.
Recall the Trigonometric Ratio below:

For csc, sec and cot - they are reciprocal of sin,cos and tan.

What we know now is our hypotenuse, adjacent and opposite length.
- hypotenuse = 15
- opposite = 12
- adjacent = 9
Therefore,
As for the reciprocal of three trigonometric ratio. We just swap the numerator and denominator.

Answer
- sin = 12/15 —> 4/5
- cos = 9/15 —> 3/5
- tan = 12/9 —> 4/3
- csc = 15/12 —> 5/4
- sec = 15/9 —> 5/3
- cot = 9/12 —> 3/4
The first is non-simplifed form while the second that has the arrow pointing is the simplest form.
Let me know if you have any doubts.
Answer:
30
Step-by-step explanation:
Again there are TWO sides so it would be 50% chance of getting head, or 50% of getting tail. So it would probably be 30
