4\left(\frac{2\times 5+14}{5}-1\right)-12=3\times 14-2
Multiply both sides of the equation by 12, the least common multiple of 3,4,6.
4\left(\frac{10+14}{5}-1\right)-12=3\times 14-2
Multiply 2 and 5 to get 10.
4\left(\frac{24}{5}-1\right)-12=3\times 14-2
Add 10 and 14 to get 24.
4\left(\frac{24}{5}-\frac{5}{5}\right)-12=3\times 14-2
Convert 1 to fraction \frac{5}{5}.
4\times \frac{24-5}{5}-12=3\times 14-2
Since \frac{24}{5} and \frac{5}{5} have the same denominator, subtract them by subtracting their numerators.
4\times \frac{19}{5}-12=3\times 14-2
Subtract 5 from 24 to get 19.
\frac{4\times 19}{5}-12=3\times 14-2
Express 4\times \frac{19}{5} as a single fraction.
\frac{76}{5}-12=3\times 14-2
Multiply 4 and 19 to get 76.
\frac{76}{5}-\frac{60}{5}=3\times 14-2
Convert 12 to fraction \frac{60}{5}.
\frac{76-60}{5}=3\times 14-2
Since \frac{76}{5} and \frac{60}{5} have the same denominator, subtract them by subtracting their numerators.
\frac{16}{5}=3\times 14-2
Subtract 60 from 76 to get 16.
\frac{16}{5}=42-2
Multiply 3 and 14 to get 42.
\frac{16}{5}=40
Subtract 2 from 42 to get 40.
\frac{16}{5}=\frac{200}{5}
Convert 40 to fraction \frac{200}{5}.
\text{false}
Compare \frac{16}{5} and \frac{200}{5}.
