The top answer is right, it’s 18.
15=x-3
you’d add 3 to 3 to get rid of it (because it’s -3) and add it to also 15. 15+3= 18 so x=18
15=18-3

A school had a girl:boy ratio 5.4.

Answer:

The 982 part seems wrong. Are you sure it isn't 981?

around 436 if I use 981 instead. 982 would give a decimal and that would be kinda weird for a part human.

Step-by-step explanation:

You can divide the 205 by 5 to simplify the ratio down. 205/5 = 41. Then you can multiply by 4 to find then number of boys.

981

So you can add the 5 and 4 together to 9 and then divide 981 by 9 to get 109. Then you can multiply by 4 to get 436.

Hope this helps!
