Question

2 1/2 / 1 1/4

Answer 1

\[2\frac{ 1 }{ 2 }\div 1\frac{ 1 }{ 4}\] ?

Answer 2

An easy way to approach this is to change the mixed numbers into fractions alone.
You would get \[\frac{ 5 }{ 2}\div \frac{ 5 }{ 4}\]

Answer 3

Then you simply "Keep it, Change it, Flip it."

By this, I mean, keep the first fraction, change the division sign to multiplication and flip the second fraction. So,
\[\frac{ 5 }{ 2 }\times \frac{ 4 }{ 5}\]

Answer 4

Now multiply across the numerators and multiply across the denominators.
Your solution would be
\[\frac{ 20 }{ 10}\] or 2
