Write as a fraction over 100, and simplify:

\(\displaystyle \frac{132}{100} = \frac{132\div 4}{100\div 4} = \frac{33}{25}\)

Multiply by 100, and simplify:

\(\displaystyle \frac{24}{25} \times 100 = \frac{24}{25} \times \frac{100}{1} = \frac{24}{1} \times \frac{4}{1} =\frac{ 96}{1}=96\)

The correct choice is 96%.

To find the percentage, first write the values as a fraction, then convert the fraction's denominator to \(\displaystyle 100\). We can write the given values as \(\displaystyle \frac{2}{50}\), which can be converted to \(\displaystyle \frac{4}{100}\) by multiplying both the numerator and denominator by \(\displaystyle 2\). \(\displaystyle \frac{4}{100}\) is equivalent to \(\displaystyle 4\%\).

Taking 250% of a number is the same as multiplying that number by 2.5. We therefore take the product:

\(\displaystyle 750 \cdot 2.5 = 1,875\)

One way to go about solving this problem is to convert the percent into a decimal and multiply your whole number by that in order to get your answer. When converting a percent into a decimal, move the decimal point two spaces to the left:

30% = 0.30

Then, multiply this number times 150:

\(\displaystyle 150 \times 0.30 = 45\)

Your answer is \(\displaystyle 45\).

We can solve for \(\displaystyle x\) with the algebraic equation:

\(\displaystyle 0.3\cdot x=60\)

\(\displaystyle x=\frac{60}{0.3}\)

\(\displaystyle x=200\)

We can then calculate \(\displaystyle 40\%\) of \(\displaystyle x\):

\(\displaystyle 0.4\cdot200=80\)

We can convert \(\displaystyle 40\%\) to \(\displaystyle \frac{40}{100}\) or \(\displaystyle 0.4\). We can then calculate \(\displaystyle 0.4\cdot 80=32\).

\(\displaystyle 22 \frac{1}{2} \%\) of \(\displaystyle 22 \frac{1}{2}\)  can be rewritten as 

\(\displaystyle \frac{22 \frac{1}{2} }{100} \times 22 \frac{1}{2}\)

\(\displaystyle = \frac{45}{2} \times \frac{1}{100} \times \frac{45}{2}\)

\(\displaystyle = \frac{45 \times 1 \times 45}{2 \times 100 \times 2}\)

\(\displaystyle = \frac{2,025}{400} = \frac{2,025 \div 25}{400\div 25} = \frac{81}{16} = 5 \frac{1}{16}\)

 \(\displaystyle 8\frac{1}{3} \%\) of \(\displaystyle 666 \frac{2}{3} \%\) is equal to:

\(\displaystyle \frac{8 \frac{1}{3} }{100} \times 666 \frac{2}{3} \%\)

\(\displaystyle = \frac{ \frac{25}{3} }{100} \times \frac{2,000}{3}\)

\(\displaystyle = \frac{25}{3} \times \frac{1 }{100} \times \frac{2,000}{3}\)

Cross-cancel:

\(\displaystyle \frac{25}{3} \times \frac{1 }{1} \times \frac{20}{3}\)

\(\displaystyle = \frac{500}{9} = 55\frac{5}{9}\)

Taking 8,000%, as a decimal, is equivalent to multiplying it by \(\displaystyle 8,000 \div 100 = 80\), so 8,000% of 9,000 is equivalent to 

\(\displaystyle 80 \times 9,000 = 720,000\).
