Question

a satin ribbon that was 12/7 meter long tore in to 2 piece.one piece is 1/3 meter long . How long is the other piece? give the answer in Step by step.​

Answer 1

Answer:

29/21 or 1 $\frac{8}{21}$

Step-by-step explanation:

Because there was only 2 pieces there is only one answer to this question. One of the pieces is 1/3 meters long so subtracting it from 12/7 gives 29/21 meters long which is also 1 $\frac{8}{21}$. You're only tearing the ribbon into 2, you're not losing any material so together they still have to add up to 12/7, which is why you subtract.

12/7 - 1/3

= 3(12/7) - 7(1/3)

= 36/21 - 7/21

= (36-7)/21

= 29/21
