Explanation:
1)
![(7)/(9) * x = 21](https://img.qammunity.org/2021/formulas/mathematics/high-school/u5sucvk8ki7f49u6thfhssvdcr9tcaces8.png)
2)
![* (9)/(7)](https://img.qammunity.org/2021/formulas/mathematics/high-school/u2ngkm99y32wbu7rb0a3p3twrsnlqgumwt.png)
∧ The fraction gets cross-multiplied and gets removed. 21 is then multiplied by 9/7
3)
![x = 21 * (9)/(7)](https://img.qammunity.org/2021/formulas/mathematics/high-school/vj2u9287yuf01ihsjmtgwume0obmuet6sv.png)
4)
![7 * x =21 *( (9)/(7) * (7)/(1) )](https://img.qammunity.org/2021/formulas/mathematics/high-school/t17jqcttqrprf7ne4nnc8sxk150l5xuzg1.png)
∧ The 9 / 7 gets multiplied by 7 / 1 to become 9. 7 is then multiplied by x
5)
![7x = 21 * 9](https://img.qammunity.org/2021/formulas/mathematics/high-school/chf5bu0ul9qk1ugmqz5h5zz9hfvywosd8p.png)
6) Simplify 21 * 9 to 189
7)
![7x = 189, becomes, (7x)/(7) = (189)/(7)](https://img.qammunity.org/2021/formulas/mathematics/high-school/6h6rv5l7izhl6xza4e8badloqya1x9h2ys.png)
8) Simplify to
, where x = total number of chocolates
9)
milk chocolates
