mr thompson spends 1/5 of his salary on rent, 1/6 on food, 1/10 on clothing and 1/15 on entertainment. What fraction of his salary is left

FRACTION OF SALARY LEFT = FRACTION OF TOTAL SALARY - FRACTION OF RENT - FRACT OF FOOD - FRACTION OF CLOTHING - FRACTION OF ENTERTAINMENT
1 - 1/5 - 1/6 - 1/10 - 1/15
30/30 - 6/30- 5/30 - 3/30 - 2/30 = 14/30 = 7/15

1-(1/5+1/6+1/10+1/15)=
LCM=30
(30*1/1)-[(6*1/5)+(5*1/6)+(3*1/10)+(2*1/15)]=[(30/30)-(6/30+5/30+3/30+2/30)]=14/30=7/15=ans

Lets assume x is the salary of thompson is x. Hence we have
$x-\frac{1}{5}x-\frac{1}{6}x-\frac{1}{10}x-\frac{1}{15}x$x−15 x−16 x−110 x−115 x
we need to find a number that is dividable by 5, 6, 10 and 15 so the smallest number that is dividable by all four of those is 30.
$\frac{30-6-5-3-2}{30}x=\frac{14}{30}x=\frac{7}{15}x$30−6−5−3−230 x=1430 x=715 x
