Answer:
15
Explanation:
We have been told:
- Alex made 18 free throws
- Quinn made 1/6 less than that
Therefore, to find the number of throws Quinn made, we need to find 1/6 of 18, then subtract this from 18 (the number of throws Alex made).
![\begin{aligned}\sf \frac16\:of\:18 &=\sf \frac16 * 18\\\\ & = \sf (1 * 18)/(6)\\\\ & = \sf(18)/(6)\\\\ & =\sf18 / 6\\\\ & =\sf3\end{aligned}](https://img.qammunity.org/2023/formulas/mathematics/middle-school/i88y17eyj3h3425ian10ruhjj6vnmm3xvq.png)
Now we have calculated 1/6 of 18, we can subtract it from 18 to find the number of throws Quinn made:
⇒ Number of throws Quinn made = 18 - 3 = 15
