Question

If a 40 m rope is cut into two pieces in the ratio 3:5, how long is each piece?

I tried it but I checked it and it was wrong, please help.

If the pieces are in the ratio 3:5 it means that if you divide the rope into 3+5=8 pieces, one part has 3 lengths, and the other has 5.

So, since 40/8 = 5, the pieces have lengths 15 and 25

15:25 = 3:5
