Question
Which set of statements shows the correct steps to find 70 percent of 82?
Write 70 percent as 7 ´ 1 percent. Write 1 percent as StartFraction 1 Over 100 EndFraction. Then, find StartFraction 1 Over 100 EndFraction of 82: 82 times StartFraction 1 Over 100 EndFraction = StartFraction 82 Over 100 EndFraction = 0.82. Multiply 0.82 by 7 to get 5.74. So, 70 percent of 82 is 5.74.
Write 70 percent as StartFraction 1 Over 7 EndFraction. Then, find StartFraction 1 Over 7 EndFraction of 82: 82 times StartFraction 1 Over 7 EndFraction = StartFraction 82 Over 7 EndFraction = 11.71. So, 70 percent of 82 is 11.71.
Write 70 percent as 7 ´ 10 percent. Write 10 percent as StartFraction 1 Over 10 EndFraction. Then, find StartFraction 1 Over 10 EndFraction of 82: 82 times StartFraction 1 Over 10 EndFraction = StartFraction 82 Over 10 EndFraction = 8.2. Multiply 8.2 by 7 to get 57.4. So, 70 percent of 82 is 57.4.
Write 70 percent as StartFraction 1 Over 70 EndFraction. Then, find StartFraction 1 Over 70 EndFraction of 82: 82 times StartFraction 1 Over 70 EndFraction = StartFraction 82 Over 70 EndFraction = 1.17. So, 70 percent of 82 is 1.17.
Write 70 percent as 7 ´ 1 percent. Write 1 percent as StartFraction 1 Over 100 EndFraction. Then, find StartFraction 1 Over 100 EndFraction of 82: 82 times StartFraction 1 Over 100 EndFraction = StartFraction 82 Over 100 EndFraction = 0.82. Multiply 0.82 by 7 to get 5.74. So, 70 percent of 82 is 5.74.
Write 70 percent as StartFraction 1 Over 7 EndFraction. Then, find StartFraction 1 Over 7 EndFraction of 82: 82 times StartFraction 1 Over 7 EndFraction = StartFraction 82 Over 7 EndFraction = 11.71. So, 70 percent of 82 is 11.71.
Write 70 percent as 7 ´ 10 percent. Write 10 percent as StartFraction 1 Over 10 EndFraction. Then, find StartFraction 1 Over 10 EndFraction of 82: 82 times StartFraction 1 Over 10 EndFraction = StartFraction 82 Over 10 EndFraction = 8.2. Multiply 8.2 by 7 to get 57.4. So, 70 percent of 82 is 57.4.
Write 70 percent as StartFraction 1 Over 70 EndFraction. Then, find StartFraction 1 Over 70 EndFraction of 82: 82 times StartFraction 1 Over 70 EndFraction = StartFraction 82 Over 70 EndFraction = 1.17. So, 70 percent of 82 is 1.17.

To find 70 percent of 82 correctly, we should use the following steps:
1. Write 70 percent as \( 7 \times 10\% \).
2. Write 10 percent as \( \frac{1}{10} \).
3. Then, find \( \frac{1}{10} \) of 82:
\[
82 \times \frac{1}{10} = \frac{82}{10} = 8.2.
\]
4. Multiply 8.2 by 7 to get:
\[
8.2 \times 7 = 57.4.
\]
5. So, 70 percent of 82 is 57.4.
