1/3 + 3/7
save + fun + extra

(7/21 + 9/21) = 16/21 on save and fun

Marshall divides his money into four categories.

He saves 1/3 of his money.

He gives 1/6 of his money to a charity.

He uses 1/14 of his money to buy snacks at school,

and he spends 3/7 of his money on fun.

Money he saves = $\frac{1}{3}$

Money he spends for fun = $\frac{3}{7}$

Fraction of his money he save and spend on fun = $\frac{1}{3}$ + $\frac{3}{7}$

LCD of (3 and 7) is 21

$\frac{1*7}{3*7}$ + $\frac{3*3}{7*3}$

$\frac{7}{21}$ + $\frac{9}{21}$

Denominators are same so we add the numerators

$\frac{16}{21}$
