Answer:
2/5 m or 4 dm
Step-by-step explanation:
The fraction 4/10 can be reduced by removing a factor of 2 from numerator and denominator. The length could be expressed as 2/5 m.
The metric system has unit prefixes that make it easy to choose appropriate units for almost any measurement. Apparently Christina wants to use 1/10 m as her unit of measurement. That length is also called a "decimeter." So, Christina's measurement could be expressed in very simple form as 4 dm.
_____
A decimeter is not a particularly common unit in everyday use, though it is reasonably useful for many purposes.* More conventionally, lengths in that range are expressed in centimeters, so Christina's measurement could also be described as 40 cm.
____
* I like units of decimeters for volume calculations, because a cubic decimeter is 1 liter.
Step-by-step explanation:
you need to solve this using fractions.
Example :
It takes 3 men 8 hours to build a wall. How long would it take 4 men to build the same wall?
For 3 men: It is 1 wall divided by 8 hours, which is 1/8.
For 1 man: It is 1/8 divided by 3, which is 1/24.
For 4 men: It is 1/24 multiplied by 4, which is 1/6, = 6 hours.
