Answer:

Fraction Form: \frac{11}{24}

Decimal Form: 0.4583

Step-by-step explanation:

Apply the fraction rule: \frac{-a}{b} = - \frac{a}{b}

\frac{-5}{12} = - \frac{5}{12}

- \frac{5}{12} + \frac{7}{8}

Least Common Multiple (LCM) of 12 and 8: 24

- \frac{5}{12} x  \frac{2}{2} = - \frac{10}{24} \\\\\frac{7}{8} x  \frac{3}{3} = \frac{21}{24} \\\\- \frac{10}{24} + \frac{21}{24}

Apply the fraction rule:

\frac{a}{c} + \frac{b}{c}= \frac{a + b}{c}\\\\\frac{-10 + 21}{24} \\\\-10 + 21 = 11\\\\\frac{11}{24}

Calvin had 30 minutes in time-out. For the first 23 1/3 minutes, Calvin counted spots on the ceiling. For the rest of the time,
scoundrel [369]

Answer: \frac{20}{3}\ minutes or 6 \frac{2}{3}\ minutes

Step-by-step explanation:

For this exercise you can convert the mixed number to an improper fraction:

1. Multiply the whole number part by the denominator of the fraction.

2. Add the product obtained and the numerator of the fraction (This will be the new numerator).

3. The denominator does not change.

Then:

23\frac{1}{3}= \frac{(23*3)+1}{3}= \frac{70}{3}\ minutes

You know that he had 30 minutes in time-out, he counted spots on the ceiling for \frac{70}{3} minutes and the rest of the time he made faces at his stuffed tiger.

Then, in order to calculate the time Calvin spent making faces at his stuffed tiger, you need to subract 30 minutes and \frac{70}{3} minutes:

30\ min-\frac{70}{3}=(\frac{3(30)-70}{3})=\frac{20}{3}\ minutes or 6 \frac{2}{3}\ minutes
