Fraction of total are red beans =
Number of red beans =
Fraction of total are green beans =
Number of green beans =
Fraction of total are yellow beans =
Number of yellow beans =
Fraction of total are orange beans =
Number of orange beans =
Number of black beans = 6

Multiplying each term by 12 to remove fractions.
combining like terms.
Subtracting both sides by
∴
Total number of Jelly beans in the sack = 72
Number of red beans =
Number of green beans =
Number of yellow beans =
Number of orange beans =
number of black beans = 6
