HELP ASAP!!! I SUCK AT MATH AND I DON’T understand this!!!
anyanavicka [17]

Answer:

Part A:

\frac{13}{20}

Part B:

\frac{1}{39}

Step-by-step explanation:

The total number of candies is 40.

10 + 14 + 4 + 12 = 40

14 are Butterfinger and 12 are Crunch.

14 + 12 = 26

\frac{26}{40}

\frac{26}{40}=\frac{26/2}{40/2}=\frac{13}{20}

\frac{10}{40} =\frac{10/10}{40/10} =\frac{1}{4}

40 - 1 = 39

\frac{4}{39}

\frac{1}{4} × \frac{4}{39}

\frac{1}{39}
