RATIOS A3

If 3:2 = 11:B; Find the value of B.

Solution

3   =  11                            [cross multiply]
2       B

x B = 11 x 2

3B = 22


3B = 22                      [divide by 3 on both sides]
3        3

B =  22                      
          3

B = 71/3



Hence the value of B is 71/3
