1st you add up all the marbles so we got 15 so the answe will be out of 15 then next we add up nhe number of yellow and purple marbles 5+3= 8 so the answe will be 8/15
You have to be very careful how you set this up. For every girl (who counts as 1) there are 3 boys (who count as 3). The total number in the proportion is 3 + 1 =4. You are given a total, but that is both boys and girls. That's why you need the 4.
3/4 = x / 236 Cross multiply
4x = 3 * 236
4x = 708 Divide by 4
x = 708/4
x = 177
There are 177 boys at the school and 236 - 177 = 59 girls.

Answer:
149.5, 150.5 , 151.5, 152.5
Step-by-step explanation:
n+(n+1)+(n+2)+(n+3)= 604
Combine Like Terms
4n + 6 = 604
Subtract 6
4n = 598
Divide by 4
n=149.5
Check Your Work:
149.5+150.5+151.5+152.5 = 604
Use a ruler for this problem. Take a picture of the measurement & then I could help you.
