Question 9 (Multiple Choice Worth 3 points)

[3.07] MA.7.A.5.2

Jarvis and his family took a road trip. His dad drove for the first half of the trip. His mom drove for two-thirds of the remaining time, and then Jarvis drove the rest of the way. If the total trip took 6 hours, how long did Jarvis drive?

Question 10 (Multiple Choice Worth 3 points)

[3.02] MA.7.A.5.1

Which shows two ninety-ninths as a decimal?

zero point zero two, with a bar over the two

zero point zero two with a bar over the entire decimal

zero point zero two zero with a bar over the digits after the decimal point

zero point zero two with a bar over the digits after the decimal point

Answer

1. 3 times the reciprocal of three-fifths: 5/3 x 3= 5 the threes cancel each other out

2. Ten and two-thirds inches of rainfall in one month, which is six and one-third inches more than the average

The word “is” represents the = sign

The words “more than” represent the add + sign

ten and two-thirds = six and one-third inches + the average

10 ? = 6 ? + average

Subtract 6 ? from both sides

4 ? = average

- Subtract six and one-third.

3. If the total trip took 3 hours and his dad drove the first half--- his dad drove 3 hours

His mom drove 2/3 of the leftover time (6-3) so 2/3 x 3= 2 hours

total time alotted for is 5 hours. 6-5 = 1 hour. He drove for 1 hour

4. zero point zero two with a bar over the digits after the decimal point2/99 = 0.02020202020202020202020202 so the line would be over the repeating part .02
