Question

I need help on #3 #5 and #6

Answer 1

3. First start by making the mixed number into an improper fraction


15/5 butter for 1 batch; 15/4 batches


then simply multiply


11 and 1/4 cups of butter are needed to make 3 and 3/4 batches.


5. (I might not have gotten this one right btw) First you need to figure out how many books she read in one day.

6/5 = 1.2
Then multiply this number by 10

1.2 * 10 = 12
then multiply 1.2 * 20

1.2 * 20 =24

So Mr Barker can read 12 books in 10 days, and 24 books in 20 days.


6. change the mixed numbers to improper fractions

7/4 cups of cereal and 9/2 bowls of cereal

multiply the fractions together

7/4 * 9/2 = 63/8

change back to a mixed number

7 and 7/8

So Mr. N eats 7 and 7/8 cups of cereal every week (who measures out their cereal each morning anyway :), hope this helps!)
