Question

Use the model to complete the sentence 0.25 ÷ 5 = _______.

Answer 1

Answer:

From the image below

$0.25=\frac{25}{100}$

Hence,

$\begin{gathered} 0.25\div5 \\ =\frac{25}{100}\div5 \end{gathered}$

Using the method of division below, we will have

$\frac{a}{b}\div\frac{c}{d}=\frac{a}{b}\times\frac{c}{d}=\frac{ac}{bd}$

Hence,

By applying the principle, we will have

$\begin{gathered} \frac{25}{100}\div\frac{5}{1} \\ =\frac{25}{100}\times\frac{1}{5} \\ =\frac{5}{100} \\ =0.05 \end{gathered}$

Hence,

The complete statement is

$0.25\div5=0.05$
