John jogs 2 7/10 miles to the park. Marsha jogs 4/5 miles to the park. How much farther does John jog?

Elden [556K]

Answer:

1.9 miles.

Step-by-step explanation:

John jogs 2 7/10 miles to the park. Marsha jogs 4/5 miles to the park.

Convert the fractions into decimals:

2 7/10 = 2.7

4/5 = 0.8

Subtract '0.8' from '2.7':

$2.7-0.8=1.9$

John should jog 1.9 miles farther than Marsha.

Hope this helps.

I don't understand what you mean by "720 7 7 to the 4 over 5 power", but for "the fourth root of 7 to the fifth power 7 to the 5 over 4 power" it would be 7^5 (seven to the power of 5)

Answer:

The greatest number of flowers that could be in a bouquet is 9 flowers

Step-by-step explanation:

We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

The factors of 27 are: 1, 3, 9, 27

Then the greatest common factor is 9.
