Answer:
See attachment
Explanation:
A) We draw the number line as shown in the attachment with intervals of 0.2 from 0 to 2.
B) Observe that, from 0 to 0.2 you move one units to get to 0.2.
From 0 to 2, on the number line with intervals of 0.2, you move 10 units from 0.
This means that:
![2 = 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2 + 0.2](https://img.qammunity.org/2021/formulas/mathematics/high-school/uufluqcxnyr83yurmokznt5h3liv90yx1y.png)
This gives us:
![2 = 0.2(1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/5utjpskxvg60urm396utye8478ty5t93ep.png)
Then finally we have:
![2 = 0.2(10)](https://img.qammunity.org/2021/formulas/mathematics/high-school/o20d7sl785muqh64ss2pqxfb62t2xti2xj.png)
By the commutative property of multiplication:
![2 = 10 * 0.2](https://img.qammunity.org/2021/formulas/mathematics/high-school/zb3dovd0d4of0h8bsbcmccd0glp4jv1g09.png)
