Answer

Explanation:

Step1: Recall fraction formula

A fraction is $\frac{\text{part}}{\text{whole}}$. Here, the part is the number of blue - cube picks and the whole is the total number of picks.

Step2: Identify part and whole

The total number of picks is 50 (the whole), and the number of blue - cube picks is 42 (the part).

Step3: Write the fraction

The fraction of blue - cube picks is $\frac{42}{50}$. Simplifying this fraction by dividing both the numerator and denominator by 2, we get $\frac{21}{25}$.

Answer:

$\frac{21}{25}$
