8 0

Answer:

there are 18 girls

Step-by-step explanation:

for every 2 boys there are 3 girls

so then you can say 2/5 of the class are boys and 3/5 are girls

and you have to calculate 3/5 of 30 so you have to divide 5 and then multiply by 3 so 30 divided by 5 is 6 the n multiply 6 by 3 and the answer is 18.

Hope this helps
