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

$\frac{4}{39}$

$\frac{1}{4}$ × $\frac{4}{39}$

$\frac{1}{39}$

Well, their speeds are ( $V_1$ is Jack's speed, and $V_2$ is Richard's.
$V_1 = \frac{1}{5} houses/day \\ V_2 = \frac{1}{7} houses/day \\ V = V_1 + V_2 = \frac{1}{5}+\frac{1}{7} = \frac{7+5}{35} = \frac{12}{35}$
They, together, can paint 12 houses in 35 days. To get a single house, we only have to calculate $\frac{35}{12}$ which is very close to 3 (a bit below)
