Question

1. write an equation by using multiplication to show $\frac{2}{10}=\frac{20}{100}$. 6. for each figure, draw all lines of symmetry. circle any figure that does not have a line of symmetry.

Explanation:

Step 1: Multiply numerator and denominator by 10

To show $\frac{2}{10}=\frac{20}{100}$, we multiply the numerator and denominator of $\frac{2}{10}$ by 10.
$\frac{2}{10}\times\frac{10}{10}=\frac{2\times10}{10\times10}=\frac{20}{100}$

Step 2: Analyze lines of symmetry for pentagon

A regular pentagon has 5 lines of symmetry. Each line passes through a vertex and the mid - point of the opposite side.

Step 3: Analyze lines of symmetry for parallelogram

A non - rectangular parallelogram has 0 lines of symmetry.

Step 4: Analyze lines of symmetry for the arrow - like shape

The given arrow - like shape has 0 lines of symmetry.

Answer:

1. Equation: $\frac{2}{10}\times\frac{10}{10}=\frac{20}{100}$
2. Pentagon: 5 lines of symmetry
3. Parallelogram: 0 lines of symmetry (circle it)
4. Arrow - like shape: 0 lines of symmetry (circle it)
