Finding the value of the second variable when the first variable is equal to one and then multiplying the second variable by the first variable of each answer will always work in this situation (two variable).
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.
3/4 / 5 = 3/4 / 5/1 = 3/4 * 1/5 = 3/20 of a gallon in each pitcher
