Answer :
"keep-change-flip" is a strategy used to dividing fractions.
always change the mix fraction to a improper fraction and you slove.
I'll do the first one and the rest is basically done the same way.
[tex] \frac{3}{4} \div 2 \frac{5}{8} = \frac{3}{4} \times \frac{21}{4} = \frac{3}{4} \times \frac{4}{21} = \frac{1}{7} [/tex]
for the last fraction equation I cross multiply the 4 divided into 4 gives you 1 and the 3 divided into 21 gives you 7.
