Explanation:

1) Part A

Step1: Identify blue and red counts

Blue = 12, Red = 18

Step2: Write ratio as fraction

$\frac{12}{18}$

Step3: Write as "to" form

12 to 18

Step4: Write as colon form

12 : 18 (or simplify to 2 : 3, 2/3, 2 to 3)

It's part - to - part because we're comparing two parts (blue and red) of the crayons, not a part to the whole (30 crayons).

Step1: Calculate total fruits

Total = 8 + 6+10 = 24

Step2: Find ratio of apples to total

Apples = 8, so ratio is $\frac{8}{24}$ (simplify to $\frac{1}{3}$)

Answer:

$\frac{12}{18}$, 12 to 18, 12 : 18 (or simplified forms like $\frac{2}{3}$, 2 to 3, 2 : 3)

1) Part B
