### Out of the 200 students in the 7th grade, 170 went on the field trip.  What percent did NOT go on the field trip?

• A.

15%

• B.

85%

• C.

10%

• D.

30%

B. 85%
Explanation
The percentage of students who did NOT go on the field trip can be calculated by subtracting the percentage of students who went on the field trip from 100%. In this case, since 170 out of 200 students went on the field trip, the percentage of students who did NOT go on the field trip is 100% - (170/200) * 100% = 85%.

### Jessica has \$4.00 in her pocket.  This is 10% of her monthly allowance.  What is her monthly allowance?

• A.

\$400.00

• B.

\$40

• C.

\$10

• D.

\$100

B. \$40
Explanation
Jessica has \$4.00 in her pocket, which is 10% of her monthly allowance. To find her monthly allowance, we can set up a proportion: 10% is to \$4.00 as 100% (or the whole) is to the unknown monthly allowance. Solving this proportion, we find that the monthly allowance is \$40.

### 25% of \$3.20 is how much?

• A.

\$0.25

• B.

\$0.08

• C.

\$0.80

• D.

\$8.00

C. \$0.80
Explanation
To find 25% of \$3.20, you can multiply \$3.20 by 0.25. This is because 25% is equivalent to 0.25 as a decimal. When you multiply \$3.20 by 0.25, you get \$0.80. Therefore, \$0.80 is 25% of \$3.20.

### What percent of 200 is 0.5?

• A.

0.25%

• B.

25%

• C.

2.5%

• D.

250%

A. 0.25%
Explanation
To find out what percent of 200 is 0.5, we can set up a proportion. Let x be the unknown percent. The proportion can be written as x/100 = 0.5/200. Cross-multiplying gives us x = (0.5/200) * 100. Simplifying further, x = 0.25%. Therefore, 0.25% is the correct answer.

### 1% of what number is 7?

• A.

70

• B.

0.07

• C.

14.28

• D.

700

D. 700
Explanation
To find 1% of a number, we divide the number by 100. In this case, we need to find a number where 1% of it equals 7. So, we can set up the equation: (1/100) * x = 7. Solving for x, we multiply both sides by 100, which cancels out the denominator, and we get x = 700. Therefore, the correct answer is 700.

Rate this question:

### What percent of 45 is 72?

• A.

• B.

160%

• C.

62.5%

• D.

127%

B. 160%
Explanation
The correct answer is 160%. To find the percentage, we divide the given number (72) by the total number (45) and multiply by 100. In this case, (72/45) * 100 = 160%. This means that 72 is 160% of 45.

Explanation
To find the percentage of one number in relation to another number, we divide the first number by the second number and then multiply by 100. In this case, dividing 13 by 65 gives us 0.2, and multiplying by 100 gives us 20%. Therefore, 20% is the correct answer.
