Question

do you know how?
for 2-3, write and solve a
multiplication equation.
2.

Explanation:

Step1: Analyze the diagram

Each circle is divided into 6 parts, and the shaded part is $\frac{2}{6}$ (simplify to $\frac{1}{3}$). There are 2 such circles. So the multiplication equation is $2\times\frac{2}{6}$ (or $2\times\frac{1}{3}$).

Step2: Solve the equation

Simplify $\frac{2}{6}$ to $\frac{1}{3}$ first. Then $2\times\frac{1}{3}=\frac{2\times1}{3}=\frac{2}{3}$. Or directly calculate $2\times\frac{2}{6}=\frac{4}{6}=\frac{2}{3}$.

Answer:

The multiplication equation is $2\times\frac{2}{6}=\frac{2}{3}$ (or $2\times\frac{1}{3}=\frac{2}{3}$), and the solution is $\frac{2}{3}$.
