\left(\frac{30}{15}+\frac{7}{15}-4\right)\left(8+\frac{16}{23}-10\right)
Convert 2 to fraction \frac{30}{15}.
\left(\frac{30+7}{15}-4\right)\left(8+\frac{16}{23}-10\right)
Since \frac{30}{15} and \frac{7}{15} have the same denominator, add them by adding their numerators.
\left(\frac{37}{15}-4\right)\left(8+\frac{16}{23}-10\right)
Add 30 and 7 to get 37.
\left(\frac{37}{15}-\frac{60}{15}\right)\left(8+\frac{16}{23}-10\right)
Convert 4 to fraction \frac{60}{15}.
\frac{37-60}{15}\left(8+\frac{16}{23}-10\right)
Since \frac{37}{15} and \frac{60}{15} have the same denominator, subtract them by subtracting their numerators.
-\frac{23}{15}\left(8+\frac{16}{23}-10\right)
Subtract 60 from 37 to get -23.
-\frac{23}{15}\left(\frac{184}{23}+\frac{16}{23}-10\right)
Convert 8 to fraction \frac{184}{23}.
-\frac{23}{15}\left(\frac{184+16}{23}-10\right)
Since \frac{184}{23} and \frac{16}{23} have the same denominator, add them by adding their numerators.
-\frac{23}{15}\left(\frac{200}{23}-10\right)
Add 184 and 16 to get 200.
-\frac{23}{15}\left(\frac{200}{23}-\frac{230}{23}\right)
Convert 10 to fraction \frac{230}{23}.
-\frac{23}{15}\times \frac{200-230}{23}
Since \frac{200}{23} and \frac{230}{23} have the same denominator, subtract them by subtracting their numerators.
-\frac{23}{15}\left(-\frac{30}{23}\right)
Subtract 230 from 200 to get -30.
\frac{-23\left(-30\right)}{15\times 23}
Multiply -\frac{23}{15} times -\frac{30}{23} by multiplying numerator times numerator and denominator times denominator.
\frac{690}{345}
Do the multiplications in the fraction \frac{-23\left(-30\right)}{15\times 23}.
2
Divide 690 by 345 to get 2.
