A bag contains 10 white balls and 6 yellow balls. We need to add 112 balls to the bag and keep the ratio the same. How many of each do we need to add.
- What's the correct formula to use?
Final total number of balls
=10+6+112=128
Half of them would be 64.
You will need 64 white and 64 yellow.
I'll leave you to figure out how many of each colour to add.
We need to keep the ratio 10:6
112 = 16*7, so we need to add
10*7 = 70 white balls
6*7 = 42 yellow balls
Thanks Steve. Oversight on my part.
Yes, Steve is right.

THANK YOU!!!!!!!!!!!!!!!
To solve this problem, we can set up a proportion to maintain the same ratio of white balls to yellow balls.
The correct formula to use is:
White balls / Yellow balls = (White balls + Additional white balls) / (Yellow balls + Additional yellow balls)
In this case, since the bag initially contains 10 white balls and 6 yellow balls, we have:
10 / 6 = (10 + Additional white balls) / (6 + Additional yellow balls)
We can use this formula to find the number of additional white balls and additional yellow balls needed.
