Answer:
yes
Step-by-step explanation:
you see we need to make pairs and then we divide each one by square numbers and I have given picture
I think the answers is 80
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys
Your answer is 75, hope this helps you!
Add the numbers they gave you and subtract it from the total to get the unknown so 100-(24+42)=34 as a decimal it will be .34 and as a percent it is 34%.
