b) Using one question from questions 6 or 7 on page 202 of the textbook, explain two ways to multiply a fraction by a whole number.
6a)
<--- First way
<--- Second way
c) Using one question from questions 4 or 5 on page 208 of the textbook, explain how to divide a fraction by a whole number.
5a)
d) Pick one word problem from questions 6-12 on page 208 of the textbook.
A pitcher of orange juice is 2/3 full. If four students equally share the juice, what fraction of the full pitcher does each student get?
PART 2
1. Fraction x Fraction.
so the question is 2/3 X 5/6 = 10/18
How did i get 10/18 as the answer? Well first of all you need to do is multiply the numerator (2) with the numerator (5) so 5 X 2 equals 10. and multiply the denominator by the denominator. so 3 X 6 equals 18. Then if you can you put it in lowest terms which is 5/9 because if you divide 10 and 18 by 2 that's what you get.

2. Fraction x Mixed Fraction.
The question is 2/5 X 1 1/5 = 12/25
So what you need to do first is make the mixed fraction into a improper fraction. So what you do is you multiply the denominator with the whole number then you just add the numerator. for example.. ( 5 X 1 + 1 = 6 ). After that you have your improper fraction so you just multiply your new numerator with the other numerator which would be 6 x 2 = 12 and you do the same with the denominators which is 5 X 5 = 25. The whole thing would look like this... 2/5 X 6/5 = 12/25
3. Mixed Fraction x Mixed Fraction.
The question for this one is 2 3/4 X 2 3/4 = 7 9/16
To get the right answer you need to turn both of the mixed fractions into improper fractions. So what you do is you multiply the denominator with the whole number then you just add the numerator. It would look like this.. ( 4 X 2 + 3 = 11/4 ). Then you just multiply your new numerator with the other numerator which would be 11 x 11 = 121 and you do the same with the denominators which is 4 X 4 = 16. So your answer would be 121/16.. but you need to turn the mixed fraction into improper fraction so you need divide the 121 by 16. 121 goes into 16.. 7 times so that would give you 112 so you have 9 leftover and has a denominator so 16 which is now 9/16. So now the right answer is 7 9/16
The question is 2/5 X 1 1/5 = 12/25
So what you need to do first is make the mixed fraction into a improper fraction. So what you do is you multiply the denominator with the whole number then you just add the numerator. for example..
