Question 1: Convert to decimals (2 points)
Use long division to write each fraction as a decimal.
- \(\frac{7}{16}\) (1 point)
- \(\frac{5}{12}\) (1 point)
Question 2: Is it exact? (2 points)
Ethan says that \(\frac{1}{6}=0.16\) exactly. Use long division to decide whether he is correct, and write the decimal form of \(\frac{1}{6}\) correctly.
Question 3: Order temperatures (2 points)
Four overnight temperatures in degrees F are \(-2.25,\ -2.6,\ -2.2,\ -2\frac{3}{4}\). Write them in order from least to greatest.
Question 4: Add and subtract (3 points)
Evaluate.
- \(-4.8+7.35\) (1 point)
- \(-\frac{5}{6}-\frac{1}{4}\) (1 point)
- \((-\frac{3}{8})(-\frac{4}{9})\) (1 point)
Question 5: Multiply and divide (3 points)
Evaluate.
- \((-2.4): 0.8\) (1 point)
- \((-\frac{3}{4}): \frac{9}{10}\) (1 point)
- \((-1.5)\times 2\frac{2}{3}\) (1 point)
Question 6: Overnight cold (3 points)
At 8 PM the temperature at Camp Pine was \(9.5^{\circ}\text{F}\). It changed by \(-2.75^{\circ}\text{F}\) each hour for 5 hours.
- Find the total change in temperature. (1 point)
- Find the temperature after 5 hours. (1 point)
- The temperature then rises \(6.5^{\circ}\text{F}\). Find the new temperature. (1 point)
Question 7: Bank account (3 points)
Aisha's account balance is \(-\$12.40\) because it is overdrawn. She deposits $50.00 and then buys 3 items that cost $8.25 each.
