Question

A bag contains {12}
12
balls, {3}
3
of which are blue.



What percentage of the balls are not blue?

Answer 1

Answer:

75%

Step-by-step explanation:

Total number of balls = 12

Number of blue balls = 3

Number of balls that are not blue = 12-3 = 9

Percentage of balls that are not blue =

$(9 \div 12) \times 100\% \\ = (3 \div 4) \times 100 \\ = 75\%$

= 75%

Answer 2

Answer:

75%

Step-by-step explanation:

The faction of the balls that are blue is 3/12, which is the same as 25%

The balls that are not blue are the leftovered balls in the bag,

which is (12-3)/12 = 9/12 = 75%

ALTERNATE METHOD:

The faction of the balls that are blue is 3/12, which is the same as 25%

Out of 100%, 100%-25%=75% of the balls are leftovered.
