1) Find the sum of 3/5 and 2/5 2) Find the difference between 2/3 and 1/4
3). what is 5 3/10 minus 2/5
4). For the school's inframurals a group of student prepared 23 1/12 liters of lemonade to sell at the end of the day they had 3 5/8 liters left over. how many liters of lemonade were sold?
5). my mother brought 3 3/4 kg of beef
2 3/5 kg of pork and 5 1/2 kg of chicken how many kilo grams of meat did she buy

Step-by-step explanation:

1) 3/5 + 2/5 = 5/5 or 1

2) to do this problem you need to make the denominators the same

(2/3)4 (1/4)3 8/12- 3/12. = 5/12

3)likewise here, you only have to change one denomimator

5 3/10 - (2/5)2

5 3/10 - 4/10

now to make this easiee for myself I prefer to make it a mixed number so 5(10)+ 3 = 53/10

53/10 - 4/10 = 49/10 then we convert this back to a mixed number and thus

5 3/10 - 2/5 = 4 9/10

4) 23 (1/12)2 - x = (3 5/8)3

23 2/24 - x = 3 15/24

- 3 15/24 +x = -3 15/24 + x

19 21/24 = x

simplify 19 7/8 liters sold

5) 3 3/4 + 2 3/5 + 5 1/2 = 11 17/20
