A team of students lined up dominoes on the gym floor. Of the 100 dominoes they used, 75 fell over. What percentage of the dominoes fell over?
[tex]\large\tt{Solution:} \\ [/tex]
proportion to solve for n;
[tex]\large\tt{ \frac{75}{100} = \frac{n}{100} } \\ \\ \large\tt{ 75 \: · \: 100 = 100n} \\ \\ \large \tt{7,500 = 100n} \\ \\ \large \tt{7,500 \div 100 = 100n \div 100} \\ \\ \large \tt{75 = n}[/tex]
[tex] \large \tt{final \: answer :} \\ [/tex]
75% of the dominoes fell over.
