Ratio and Proportion: 200: X:: 100: 0.8 (Enter numeric value only.)

First convert the mixed fraction into improper fraction as follows

\(3 2/9=\frac{\left(3\ast9\right)+2}{9}=\frac{27+2}{9}=\frac{29}{9}\)

Then, multiply the fractions

\(9/16 x 2 2/7=\frac{\mathbf{9}}{\mathbf{16}}\\mathbit{ast}\frac{\mathbf{29}}{\mathbf{9}}=\frac{\mathbf{29}}{\mathbf{16}}\)

9 cancels with 9 and the resulting product is 29/16 which simplifies to 1 13/16.

First convert 9 ½ to improper fraction as

\(9\frac{1}{2}=\frac{\left(9\ast2\right)+1}{2}=\frac{18+1}{2}=\frac{19}{2}\)

Use 1 pint =16 ounces to convert between pints and ounces

\(\frac{19}{2}\ pints\ast\frac{16\ ounces}{1\ pint}=152\ ounces\)

To convert a decimal to a fraction multiply it by 100

\(0.897\ast100=89.7% \)

The number of boys in a class is 60% of 45 students

Convert 60% to fraction and carry out the multiplication as follows

\(\frac{60}{100}\ast45=27\ boys\)
