Check now.Justas BagdonasAnswered 2 years agoA ribbon was cut into 2 pieces whose lengths are in the ratio 3:5. One piece was longer by 4 cm. What are the lengths of the two pieces?Firstly, LET's mark the shorter piece as 3x and the longer piece 5x as we don't KNOW the exact lengths but only the ratios.We know that the longer piece is longer than the shorter one by 4cm. Or we can SAY that if you lenghten the shorter piece by 4cm, you will have the both pieces equal so we can say that 3x+4=5x. Now let's solve it.3x+4=5x5x-3x=42x=4x=2Now the short piece is 3x , so 3*2=6(cm) and the long one is 5*2=10(cm) |
