Hey I need help so I came here I usually only check my answers by its urgent.
8. Which ratio can be used to convert meters to kilometers?
A.100km/1m
B.1,000km/1m
C.1km/1,000m
D.1km/10m
x meters * 1 km/1000 meters = x/1000 km
There are two ways to think about this sort of conversion .
I do it the physics/engineering way
anything /same thing = 1
so does not change the quantity, only the name.
in other words 1000m/1 km is one and 1 km/ 1000 m is aalso 1, same top and bottom
so if I have x meters multiply by 1km/1000 m , only changes name to km
if I have y km multiply by 1000 m/km , only changes name to meters
.................................................................
also a math way:
x meters / y kilometers = 1000 meters / 1 km
so
1000 y = 1 x
y = x/1000
thx Damon
To determine the ratio that can be used to convert meters to kilometers, we need to evaluate the relationship between the two units.
First, we need to understand that there are 1,000 meters in 1 kilometer (km). This means that if we divide a given number of meters by 1,000, we can convert it to kilometers.
With this in mind, let's examine the options provided:
A. 100km/1m: This ratio implies that there are 100 kilometers in 1 meter. This is not correct because it suggests that 1 meter is larger than 1 kilometer, which is not the case. Therefore, we can eliminate option A.
B. 1,000km/1m: This ratio implies that there are 1,000 kilometers in 1 meter. This is also not correct because, as mentioned earlier, 1 kilometer is equal to 1,000 meters. So, we can eliminate option B.
C. 1km/1,000m: This ratio states that 1 kilometer is equal to 1,000 meters. This is the correct conversion ratio since it aligns with the information we know about the relationship between the two units. Therefore, option C is the correct choice.
D. 1km/10m: This ratio implies that 1 kilometer is equal to 10 meters. This is not the case, so we can eliminate option D.
In conclusion, the correct ratio to convert meters to kilometers is C. 1km/1,000m.
