Answer:
5/12
Step-by-step explanation:
She spent 1/3=4/12 and 1/4=3/12. In total 4/12 + 3/12=7/12. Now subtract 7/12 from the total: 12/12 - 7/12=5/12.
First, let's find one-third of the money that she gives to her mother.
72 / 3 = $24
Second, find one-fourth of the money she spends on going out.
72 / 4 = $18
Fourth, add.
24 + 18 = $42 spent.
Now she has $30 left of the original $72. Put this into a fraction;
30/72 → 5/12
Annabelle has 5/12 ($30) of the money left.
Best of Luck!
