Ответ:
ratio will change.
Step-by-step explanation:
There are 10 girls and 8 boys in Mr. Augello's class.
The ratio of boys and girls are =![\frac{10}{8}](/tpl/images/0503/4705/66cb6.png)
=![\frac{5}{4}](/tpl/images/0503/4705/a82b7.png)
= 5 : 4
Now 5 girls and 5 more boys join the class.
so the new number of girls are 10 + 5 = 15 girls
the new number of boys are 8 + 5 = 13 boys
Now the ratio of boys and girls are =![\frac{15}{13}](/tpl/images/0503/4705/09eff.png)
= 15 : 13
Hence the ratio will change.
