Question

Blake is finding 4/5 divided by 6/7. Find his mistake if he got 30/28 or 1 1/4

Answer 1

`\bf \cfrac{4}{5}/ \cfrac{6}{7}\implies \stackrel{\bigotimes}{\cfrac{5}{4}}\cdot \cfrac{6}{7}\implies \cfrac{30}{28}~\hfill \cfrac{4}{5}/ \cfrac{6}{7}\implies\cfrac{4}{5}\cdot \stackrel{\checkmark}{\cfrac{7}{6}}\implies \cfrac{28}{30}\implies \cfrac{14}{15}`
