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:
.
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.
Since 2+8 =10 you would just have 3 left to add so it would be 10+3=13
Answer:
You are correct the answer is 48.
Step-by-step explanation:
To begin solving this question you would want to start simplifying it to make it more understandable.
3^3 is 27 which now gives you 27 + 1 x 9 +12 which makes it easier to solve.
Then you would take 1 x 9 = 9 (multiply left to right)
Now it is simple addition
27 + 9 + 12 = 48
Hopefully this helps.
