Answer:
three-fifths over three-eights equals one and three-fifths miles per hour
Step-by-step explanation:
- The martinez family walked three over five of a mile; this means they walked 3/5 of a mile.
- They walked such distance in in three over eight of an hour, this means 3/8 of an hour.
To find the rate in miles per hour, we have to divide 3/5 divided 3/8.
TO make division of fraction, we must invert the second fraction and multiply them:
The ratio is 8/5 miles per hour. In the answer given it is expressed as a mixed numer 1 3/5 that is equal to 8/5.
To transform a fraction to a mixed number, you have to divide numerator by denominator. Explanation is in figure attached.
The answer is 45.6. You multiply the beginning amount to the interest rate to understand how much interest you get. Then multiply that by the amount of years the interest is gathered. 570 * .02 = 11.4 * 4 = $45.6 interest. Add this to 570 for the original amount of 615.6.
