Question

for a science lab, each lab station needs 0.5 kg of marble chips. what is the greatest number of lab stations that can be supplied with marble chips if 12 kg of marble chips are available? a 60 b 24 c 21 d 2

Explanation:

Step1: Set up the division formula

We need to find out how many times \(0.5\) kg (amount per station) fits into \(12\) kg (total amount). The formula is \(n=\frac{12}{0.5}\), where \(n\) is the number of lab - stations.

Step2: Perform the division

We know that \(\frac{12}{0.5}=\frac{12}{\frac{1}{2}}\). Using the rule of dividing by a fraction (\(a\div\frac{b}{c}=a\times\frac{c}{b}\)), we get \(12\times\frac{2}{1}\).
\(12\times2 = 24\)

Answer:

B. 24
