Can anyone please help me solve the following math problem?
2/3 - 5/7 - 1/4 + 2
If so can you please show how you arrived at the answer?
Thank you
$\displaystyle \frac{2}{3}-\frac{5}{7}-\frac{1}{4}+2$
You must look for a common denominator
$\displaystyle \frac{2}{3}-\frac{5}{7}-\frac{1}{4}+\frac{2}{1}$
easiest way is to multiply the denominators together $\displaystyle 3\times 7\times 4 = 84$
$\displaystyle \frac{2\times 7\times 4}{84}-\frac{5 \times 4\times 3}{84}-\frac{1\times 7\times 3}{84}+\frac{2\times 84}{84}$
$\displaystyle \frac{56-60 -21+84}{84}$
$\displaystyle \frac{59}{84}$
