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.
Answer:
The correct answer is option B and D.
Step-by-step explanation:
A. Shawn owed 40% of his tuition bill, b, after paying $6.00
= 40%of (b-6)
B. The amount donated to the school was 40% more that $6.00.
Amount donated to the school = b
b=6+40% of b
C. The cost for a coat was 40% of the sum of b and $6.00.
= 40%(b+6)
D. Summer paid $6.00 more than 40% of b.
Amount by summer = x
= 40%b+6
