Change each mixed numeral into a fraction, then divide the fractions.

Do you know how to change a mixed numeral into a fraction?

anonymous · Answer

i flipp it ?

mathstudent55 · Answer

No.
We will flip the second fraction when we divide the fractions, but we're not there yet.

mathstudent55 · Answer

The first step is to rewrite both mixed numerals as fractions.
This is how you do it.
I will use a different example, not the mixed numerals from our problem.
