Answer:
7/60
Step-by-step explanation:
CLOTHES: 4/15
FOOD: 1/5
DRINK: 5/12
Common denominator between fraction of money spend on clothes and food = 15.
Food = 1/5 * 3, on top of both the numerator and denominator equals 3/15. 3/15 = 1/5. Divide by 3 and you'll be right back at 1/5.
3/15 + 4/15 = 7/15 = fraction spent on food and clothes.
Now onto drinks. We know that drinks is 5/12. We also know that for the other clothes and food, it's 7/15. Think critically. The common denominator between 5/12 and 7/15 is 60, since 12 * 5 = 60, and 15 * 4 = 60.
5/12 * 5 = 25/60
7/15 * 4 = 28/60
25/60 + 28/60 = 53/60.
Remainder, 60-53 = 7.
