Question

Which two numbers below are equal? [Select two of the numbers below.]

eighteen over fifteen

one and three over fifteen

Answer 1

take the one and three over fifteen and the three and one over fifteen and convert it to a single fraction.

1 whole is \(15\over 15\) so, \[{15 \over 15} + {3 \over 15}=???\]
