Question

Witch rational number is between -11/15 and -5/6?

answers to chose from -1, -7/10, -4/5 and -13/15

Answer 1

-4/5

Explanation:

To find this we can look for the
`LCD` between all the numbers

Here are our
`LCD's` (Least Common Denominator)

-22/30 and -25/30

It wouldn't be -1 because it isn't in between those numbers

It isn't -7/10 because if we turn it into our
`LCD` it would be -21/30 which isn't in between those numbers

It is -4/5 because if we turn in into our
`LCD` it would be -24/30 which is between those numbers

This means we have our right answer we know our last one is incorrect
