Answer:
2 3/4
Step-by-step explanation:
1/2x2=2/4
1/4+3/4=3/4
whole numbers- 1+1=2
2 3/4
6:15, I got that because every 2 out of 5 tiles is white, so it’s basically 2/5, we have to get the denominator (5) to 15. So we have to multiply 3 on both sides. Because 5*3=15 and what we do to the bottom also happens to the top. So 2*3=6. So every 6 tiles out of 15 will be white. The ratio will be 6:15. Hope that helps
Answer: 
Step-by-step explanation:
Having the following equation given in the exercise:

You can solve for "a" following this procedure:
1. You can apply the Subtraction property of equality and subtract
from both sides of the equation:

2. Now you must subtract the terms on the left side of the equation. Notice that the Least Common Denominator is "d". Then:

3. Finally, you can apply the Multiplication property of equality and multiply both sides of the equation by "b". So, you get:
