Question

ou have 30 marbles. If 12 of them are blue, what percent of the marbles that are blue?

Answer 1

Answer:

40%

Step-by-step explanation:

12/30 x 100

30 and 100 gets cancelled by 5

so.. 12/6 x 20

again it gets canceled by 2

so.. 12/3 x 10

now we multiply 12x10/3

so it becomes 120/3 which is 40

therefore 40% is the answer
