4\times 2\times \frac{1}{10}-2=6\times 3\times \frac{1}{10}-3
Multiply both sides of the equation by 12, the least common multiple of 3,6,2,4.
8\times \frac{1}{10}-2=6\times 3\times \frac{1}{10}-3
Multiply 4 and 2 to get 8.
\frac{8}{10}-2=6\times 3\times \frac{1}{10}-3
Multiply 8 and \frac{1}{10} to get \frac{8}{10}.
\frac{4}{5}-2=6\times 3\times \frac{1}{10}-3
Reduce the fraction \frac{8}{10} to lowest terms by extracting and canceling out 2.
\frac{4}{5}-\frac{10}{5}=6\times 3\times \frac{1}{10}-3
Convert 2 to fraction \frac{10}{5}.
\frac{4-10}{5}=6\times 3\times \frac{1}{10}-3
Since \frac{4}{5} and \frac{10}{5} have the same denominator, subtract them by subtracting their numerators.
-\frac{6}{5}=6\times 3\times \frac{1}{10}-3
Subtract 10 from 4 to get -6.
-\frac{6}{5}=18\times \frac{1}{10}-3
Multiply 6 and 3 to get 18.
-\frac{6}{5}=\frac{18}{10}-3
Multiply 18 and \frac{1}{10} to get \frac{18}{10}.
-\frac{6}{5}=\frac{9}{5}-3
Reduce the fraction \frac{18}{10} to lowest terms by extracting and canceling out 2.
-\frac{6}{5}=\frac{9}{5}-\frac{15}{5}
Convert 3 to fraction \frac{15}{5}.
-\frac{6}{5}=\frac{9-15}{5}
Since \frac{9}{5} and \frac{15}{5} have the same denominator, subtract them by subtracting their numerators.
-\frac{6}{5}=-\frac{6}{5}
Subtract 15 from 9 to get -6.
\text{true}
Compare -\frac{6}{5} and -\frac{6}{5}.
