Answer:
3. 4
4. 8
5. 24
Step-by-step explanation:
Equation:
Time*speed= distance
1.7(time)*22.4(speed)=38.08meter(distance)
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!)
The answer is the 2nd option of 60 degrees.
