Answer :
Since we know that 70% of then number of Jorge's songs is 294, we can represent this with the ratio 70/100 (70%) = 294/x, with x being the total number of songs Jorge has.
To solve this, cross multiply.
70 * x = 100 * 294 ----------> 70x=29400
Divide both sides by 70
x=420
To solve this, cross multiply.
70 * x = 100 * 294 ----------> 70x=29400
Divide both sides by 70
x=420
