Hello!
To calculate how much 3 cakes would cost, we must first find the cost of each individual cake.
To do this, we must divide the cost of 8 cakes by 8 cakes.
4.00 ÷ 8 = 0.5
This means that each individual cake costs $0.50. Multiply this by 3 to find the cost of 3 cakes.
0.50 × 3 = 1.50
Therefore, 3 cakes would cost $1.50.
So 12=total
7=blue
black=total-blue=12-7=5
black=5
1. 2/3 of 12 were taken out or 24/3 were taken out or 8 marbles were taken out
there is not enough info becasue it doesn't specify which ones were taken out
2. there is not enough info
3. not chosen=total-chosen=12-8=4 so 4 were chosen
