Word Problems of Converting Between Percent, Fractions, and Decimals – Examples 1

Bettie is helping her mother clean out the basement. She finds a bolt that is 3/5 of a foot in diameter.
Write \(\frac{3}{5}\) of a foot as a decimal and percent.
Solution:
Divide 3 by 5 to write as a decimal. \(3÷5=0.6\)
Multiply \(\frac{3}{5}\) by 100 to write it as a percent. \(\frac{3}{5}×100=\frac{3}{5}×\frac{100}{1}=\frac{300}{5}=60\)
So, \(\frac{3}{5}\) is equal to 0.6 and \(60%\) For additional educational resources,.
