How many fifths must be subtracted from 8 to arrive at 7.4?

three fifths

Step-by-step explanation:

1/5 is equal to 0.2, so subtracting 2/5 from eight would be the same as subtracting 0.4. Subtracting 3/5 will be the same as subtracting 0.6.

8 - 0.6 = 7.4

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
