Question
Catherine’s teacher asked her to bring 3 pieces of yarn. If each yarn is of length 0.8 meter. The total length of the yarn is ________________ decimeters.
- 22
- 23
- 24
- 25
Hint:
We are given the number of pieces of yarn brought by Catherine. It is 3. We are given the length of one yarn. It is 0.8 meter. We have to find the length of all three yarns in decimeters. For this question, we have to first find the length of three yarns and then convert the units.
The correct answer is: 24
The number of yarns is 3
The length of one yarn is 0.8 meters.
To find the length of 3 yarns, we will multiply the length of one yarn by 3.
length of 3 yarns = 3 × 0.8 meters
= 2.4 meters
Now we have to convert this value into decimeters.
For that we should know the relation between meter and decimeters.
1 meter = 10 decimeters.
So, to convert 2.4 meters into decimeters, we will multiply it by 10
length of 3 yarns = 2.4 × 10 decimeters
= 24 decimeters
So, the length of 3 yarns is 24 decimeters.
For such questions, we should know the conversion of units.
