There are only red, yellow and orange buttons in a jar the numbers of red buttons, yellow buttons and orange
buttons are in the ratio 2:4:9
work out the percentage of orange buttons in the jar​

7+4+9= 20 parts per whole

7+4+9= 20 parts per wholered: 7/20 = 35%

7+4+9= 20 parts per wholered: 7/20 = 35%yellow: 4/20 = 20%

7+4+9= 20 parts per wholered: 7/20 = 35%yellow: 4/20 = 20%orange: 9/20 = 45%

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
