Question

Owen and bell shared a granola bar. Bella ate 1/4 of the granola bar. Owen ate 1/3 of the granola bar.
how much of the granola bar did Owen and Bella leave uneaten?

Answer 1

If Bella ate 1/4 of the granola bar, then she left 3/4 uneaten.
Similarly, if Owen ate 1/3 of the granola bar, then he left 2/3 uneaten.
So, Owen and Bella left (3/4) + (2/3) = 9/12 + 8/12 = 17/12 of the granola bar uneaten.
Since this is more than 1 whole granola bar, we can say that they left 1 granola bar + 5/12 of another granola bar uneaten.
