a^-m

=> 1/a^m [By doing reciprocal]

So,

9^-2

Maya has 5/6 cup of ice cream. how many 1/4 cup servings are in 5/6 cup of ice cream
yulyashka [42]
Find the LCD (least common denominator)
\frac{5}{6}  and  \frac{1}{4}

it would be 12 (6x2=12 and 4x3=12)

so you multiply \frac{5}{6} by 2 and get \frac{10}{12}
then multiply \frac{1}{4} by 3 and get \frac{3}{12}

you get 3 WHOLE servings from \frac{5}{6} cups of icecream
