Answer:
10/21 or 0.476 miles per hour
Step-by-step explanation:
If you divide 2/3 by 1.4 (or 14/10), you will get miles per hour.
2/3 ÷ 14/10 = 2/3 x 10/14 = 20/42 = 10/21 = 0.476
The oldest son spent $10 on candy. 40 + 25 = 65 + 10 = 75 then the other 10 was spent on candy by the oldest son
5
To find the ratio you simply divide the value by the previous value
7.56/1.512 = 5
37.8/7.56 = 5
