Sanjeev ate 1/6 of cake he gave to his frend the remainder 1/5 how much did he keep

liq [111]

Step-by-step explanation:

$= 1 - ( \frac{1}{6} + \frac{1}{5} )$

$= 1 - ( \frac{5}{30} + \frac{6}{30} )$

$= 1 - \frac{11}{30}$

$= \frac{30}{30} - \frac{11}{30}$

$= \frac{19}{30}$

So, he keeps $\frac{19}{30}$
