Question

There are only red buttons, yellow buttons and orange buttons in a jar.

The number of red buttons, the number of yellow buttons and the number of orange buttons are in the ratio 7 : 4 : 9
Work out what percentage of the buttons in the jar are orange

Answer 1

45%

Explanation:

Add 7,4, and 9. You will get 20, then since they are asking for orange, divide 9 by 20, you will get 0.45 or 45%.

You are welcome!

Answer 2

orange is 9.
so 9/(7+4+9 ) times 100.
the answer is 45%
