Conifer planting

Out of the total number of 128 trees and shrubs around the school, pupils planted 1/4 in the autumn. Of these planted trees and shrubs, 3/4 were conifers. How many conifers did the pupils plant in the autumn?

Final Answer:

x =  24

Step-by-step explanation:

$$\begin{gathered} j=128\cdot \frac{1}{4}=\frac{128\cdot 1}{4}=\frac{128}{4}=32 \\ x=\frac{3}{4}\cdot j=\frac{3}{4}\cdot 32=\frac{3\cdot 32}{4}=\frac{96}{4}=24 \end{gathered}$$
