A 2 1/2 m board is to be used for making shelves. Mario made 2 shelves each using up 5/6m of board. Does he have enough left to make another requiring 4/5 m? Give the raon to your answer.

Sagot :

We will see if this inequality is true, if it is then you could:
2 1/2 - 2(5/6) ≥ 4/5
5/2 - 5/3 ≥ 4/5
5/6 ≥ 4/5 
We cross-multiply to see if it is true:
25 ≥ 24  TRUE 
Therefore you still have enough left.
