Convert \(1.5 \) to a percentage. \(1.5=\underline{\ \ \ \ \ \ \ \ \ \ }\%\)
SOLUTION: \(1.5=1+0.5\) \(=100\%+50\%\) \(=150\%\)
In conclusion, \(1.5\) to the percentage is \(150\%\).
Calculate the total percentage of vitamin B6, calcium and iron for a \(30\,\ell\) serving of cereal with \(125\text{ m}\ell\) of skimmed milk below.
SOLUTION: \(46\%+24\%+16\%=\underline{\ \ \ \ \ \ }\%\)
\(\begin{array} {rr} \small{\color{red}{1}}\quad\;\;\; \\4\;6\;\% \\2\;4\;\% \\+\quad1\;6\;\% \\\hline 8\;6\;\% \\\hline \end{array}\)
In conclusion, the total percentage of vitamin B6, calcium and iron is \(86\%\).
Jamel's rope length is \(2.5\text{ m}\) while Zainab's rope length is \(90\%\) of Jamel's rope length. How long is \(90\%\) of \(2.5\text{ m}\)?
SOLUTION:
\(90\%\) from \(2.5\text{ m}\) means \(90\%\times2.5\text{ m}\). \(90\%\times2.5\text{ m}=\underline{\ \ \ \ \ \ \ \ \ }\text{ m}\)
\(2.5\times\dfrac{90}{100}=2.25\)
In conclusion, the length \(90\%\) of \(2.5\text{ m}\) rope length is \(2.25\text{ m}\).
