Answer:

The length of the ribbons in all were 25.3 meters.

Step-by-step explanation:

Given:

Lengths of the three pieces of ribbon were 10 meters and 9 decimeters, 3 meters and 10 decimeters, and finally 10 meters and 4 decimeters.

Now, to find the length of the ribbons in all.

So, by adding the length of all three pieces we get the length of all the ribbons:

10 meters\ 9 decimeters

+3 meters\ 10 decimeters

+10 meters\ 4 decimeters.

=23 meters\ \ 23\ decimeters.

Now, converting the decimeters into meters = 23 meters + 2.3 meters = 25.3 meters.

(1 decimeter = 0.10 meter)

(23 decimeter = 2.3 meter.)

Therefore, the length of the ribbons in all were 25.3 metres.
