Question

Use a standard algorithm to calculate: 5−2/3 -3/5

Answer 1

By taking LCM of the given equation we get,

$5- \frac {2}{3}- \frac{3}{5} = 5* \frac{15}{15}- \frac {2*5}{3*5}- \frac{3*3}{5*3}$

$=\frac {75}{15}-\frac {10}{15}-\frac {9}{15}$

$= \frac{75-10-9}{15}= \frac{56}{15}$

Hence,

$5- \frac {2}{3}- \frac{3}{5} = \frac{56}{15} = 3.73333$
