Answer:
49 1/2 miles per hour
Step-by-step explanation:
To determine the average speed, we take the miles and divide by the hours
speed ÷ hours
24 3/4 ÷ 1/2
Change the mixed number to an improper fraction
24 3/4 = (4* 24+3)/4 =99/4
99/4 ÷ 1/2
Copy dot flip
99/4 * 2/1
99/2
Change to a mixed number
2 goes into 99 49 times (49*2 = 98) with 1 left over
49 1/2 miles per hour
Answer:53 dresses
Step-by-step explanation:
First of all..if one kid required 2 1/4m of cloth,what about 119 1/4m of cloth?
So u take 119 1/4m of cloth and divide it by 2 1/4m of cloth.
Then change the mixed numbers into improper fractions.
So the question will be 477/4 m divided by 9/4 m.
The second improper fraction (9/4)m will be reciprocated to be (4/9)m.
Afterwards,take 477/4 m and multiply it by 4/9 m.
The result will be 53 dresses.
