Answer

Answer:

  1. $\frac{13}{16}+\frac{3}{16}=\frac{13 + 3}{16}=\frac{16}{16}=1$
  2. First - aid can be administered by trained individuals when someone is injured or in a medical emergency.
  3. Since 1 foot = 12 inches, $96\div12 = 8$ feet.
  4. Since 1 foot = 12 inches, $48\div12 = 4$ feet.
  5. Since 1 foot = 12 inches, $144\div12 = 12$ feet.
  6. Make a common denominator: $\frac{3}{8}=\frac{6}{16}$, so $\frac{3}{8}>\frac{5}{16}$.
  7. $\frac{4}{8}=\frac{1}{2}$, they are equal.
    1. Wear safety glasses. 2. Keep hands away from the blade. 3. Secure the workpiece properly.
  9. $11\frac{1}{4}+11\frac{1}{4}=(11 + 11)+(\frac{1}{4}+\frac{1}{4})=22+\frac{2}{4}=22\frac{1}{2}$ inches.
  10. Make a common denominator: $\frac{10}{16}=\frac{5}{8}$, they are equal.
  11. $5\times3.33 = 16.65$ dollars.
  12. $3\times6.98 = 20.94$ dollars.
  13. Politely remind the person to wear safety glasses.
  14. Since 1 hour = 60 minutes, $2\times60 = 120$ minutes.

Explanation:

  1. Step1: Add numerators

$\frac{13+3}{16}$

Step2: Simplify fraction

$\frac{16}{16}=1$ 70. N/A (Answer - Explanation Format) 71. ## Step1: Use conversion factor $96\div12$ 72. ## Step1: Use conversion factor $48\div12$ 73. ## Step1: Use conversion factor $144\div12$ 74. ## Step1: Find common denominator $\frac{3}{8}=\frac{3\times2}{8\times2}=\frac{6}{16}$

Step2: Compare numerators

$\frac{6}{16}>\frac{5}{16}$ 75. ## Step1: Simplify fraction $\frac{4}{8}=\frac{4\div4}{8\div4}=\frac{1}{2}$ 76. N/A (Answer - Explanation Format) 77. ## Step1: Add whole - numbers $11 + 11=22$

Step2: Add fractions

$\frac{1}{4}+\frac{1}{4}=\frac{2}{4}$

Step3: Combine results

$22+\frac{2}{4}=22\frac{1}{2}$ 78. ## Step1: Simplify fraction $\frac{10}{16}=\frac{10\div2}{16\div2}=\frac{5}{8}$ 79. ## Step1: Multiply quantity and price $5\times3.33$ 80. ## Step1: Multiply quantity and price $3\times6.98$ 81. N/A (Answer - Explanation Format) 82. ## Step1: Use conversion factor $2\times60$
