Answer:
Dividing a whole number by a fraction you would just multiply the bottom number of the fraction by the whole number.
Step-by-step explanation:
(here is how to divide a fraction by a whole number, if you need help on that also.)
1. Turn the whole number into a fraction. ( ex: 2=2/1)
2. Multiply the fraction by the whole number fraction.
3. Multiply the tops together and the bottoms together
Dividing A Fraction By A Fraction
1. Arrange the equation
2. Keep the first fraction
3. Change the sign
4. flip the fraction
5. Multiply the tops together and the bottoms together
Answer:
x=20 and y=100
Step-by-step explanation:
Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.

Step-by-step explanation:
We have to fill the blank.
The number of permutations of n elements taken r at a time is given by the formula:

Permutation is an arrangement of subsets of a larger set in regard with order of the arrangement.
where n is the the larger set and we have to choose r items from n such that there is no repetition.
In permutation, order is important.
