Answer:
- 8 3/4
 - 2, 3
 - 4 1/2, 11 1/4
 - 9 3/4, 16 1/4
 - Y/B = 2/3
 
Step-by-step explanation:
<h3>a)</h3>
The first line is simply the sum of the two given numbers.
   3 1/2 +5 1/4 = (3+5) +(2/4+1/4) = 8 3/4
__
To find values on the remaining lines, it is convenient to find the ratios of the numbers involved. The ratio of yellow to blue is ...
   Y/B = (3 1/2)/(5 1/4) = (7/2)/(21/4) = (7/2)(4/21) = 2/3
Then ...
   Y : B : total = 2 : 3 : 5
This tells you the numbers on the second line are ...
   Y = 2; B = 3
__
The value for B on the third line is the basic ratio number multiplied by (6 3/4)/3 = 2 1/4. Then the other two numbers are ...
   Y = 2(2 1/4) = 4 1/2
   total = 5(2 1/4) = 11 1/4
__
The value for Y on the fourth line is the basic ratio number multiplied by (6 1/2)/2 = 3 1/4. Then the other two numbers are ...
   B = 3(3 1/4) = 9 3/4
   total = 5(3 1/4) = 16 1/4
_____
<h3>b)</h3>
The equation is the one we used to find the values on the second line:
   Y/B = 2/3
