Student trip fraction

Of 32 students in the class, 3/4 of the children were on the trip. Write as a fraction what part of the students stayed at home. How many students were on the trip?

Final Answer:

a =  1/4
b =  24

Step-by-step explanation:

$$\begin{gathered} n=32 \\ a=1-\frac{3}{4}=\frac{1\cdot 4}{4}-\frac{3}{4}=\frac{4}{4}-\frac{3}{4}=\frac{4-3}{4}=\frac{1}{4}=0.25 \end{gathered}$$

$b=\frac{3}{4}\cdot n=\frac{3}{4}\cdot 32=\frac{3\cdot 32}{4}=\frac{96}{4}=24$
