Question

Peter drank 2/3 liter of water Monday before going jogging. He drank 3/4 liter of water after his jog. How much water did Peter drink altogether? Write your answer as a mixed number.

Answer 1

1 and 5/12

Explanation:

2/3+3/4=17/12

17/12= 1 5/12

Answer 2

1 5/12

Explanation:

find the common factor of the denominators (3 and 4) which is 12 then just multiply the 2 in 2/3 by 3 since 12 is the third common factor for 3 and you do the same thing with 3/4, multiply the 3 by 3. then you add 8/12 + 9/12 to get 17/12 then 17 goes into 12 once plus 5 left over so as a mixed number its 1 5/12
