Question

4. 2/3 of the students in Sarah’s class are boys. Of the boys, 13 of them wear glasses. What fraction of the students are boys that wear glasses? Choose the model that matches the situation.

Answer 1

Yes let's find

The fraction is

`\\ \rm\Rrightarrow 13/2/3`

`\\ \rm\Rrightarrow 13(3)/2`

`\\ \rm\Rrightarrow 39/2`

Answer 2

39/2 of the class are boys that wear glasses

Explanation:

`\frac23 \textsf{ of the class are boys.}`

`\textsf{If 13 of them wear glasses, then} (13)/(\frac23)} \textsf{ wear glasses.}`

`13 / \frac23 =13 * \frac32=(39)/(2)`
