Can the sum of two mixed numbers be equal to 2? explain why or why not.
Answers
no it cannot because a mixed # for example would look like this 2 3/5 it will need a whole number and a fraction The reason why I say NO is because you can only have 1 mixed number in 2 and that would be 1 1/2 (1 1/2 + 1/2 = 2) And when you try again your numbers will be 1 and 1. So NO, you cannot have to mixed numbers in the number 2

If a barrel is 1/5 full and holds 16 litres how many litres will it hold when 1/2 full
Answers
16*5 = 80, that's how many litres when it's full 80/2 = 40, that's how many litres when it's half full It will hold 40 litres
You have to do 16 x 5 ( denominator ) which is 80. 80 is when it is full. SO... you have to half that giving you 40. The answer is 40
