Thinking About Fractions & Decimals 1 Here are four of the markers from the calendar pattern this month. Label each one with at least two different fraction or decimal names. 10 11 12 13 SERIE

Answer 1

Answer:

11. 40/100 = 4/10

12. 2/5 = 4/10

13. 4/10 = 8/20

Explanation:

A fraction can be written as a/b where b is the total number of divisions and a is the number of parts that you take.

So, for 11, the fraction is:

$\frac{40}{100}$

Because there are 100 parts and 40 of them are colored.

So, to find another equivalent fraction we can divide every number by 10 as:

$\frac{40\div10}{100\div10}=\frac{4}{10}$

In the same way, for 12, we get:

$\begin{gathered} \frac{2}{5} \\ or \\ \frac{2\times2}{5\times2}=\frac{4}{10} \end{gathered}$

For 13, we get:

$\begin{gathered} \frac{4}{10} \\ or \\ \frac{4\times2}{10\times2}=\frac{8}{20} \end{gathered}$
