We need to determine the number of times 0.03 cm (the thickness of ONE card) divides into 1.5 cm (the thickness of the entire deck)
In other words, we must evaluate 1.5/0.03
TIP: Rather than call up the online calculator, notice that we can take 1.5/0.03 and create an equivalent fraction
Take 1.5/0.03 and multiply numerator and denominator by 100 to get: 150/3
At this point, it's easy to see that 150/3 evaluates to 50
So, 1.5/0.03 = 150/3 = 50
Answer: B
