Question

Amy was looking at a table of conversions from meters to kilometers. The table showed that 2 kilometers are equivalent to 2,000 meters, How can she determine how many kilometers are equivalent to 8,000 meters? Explain​

Answer 1

Explanation:

Since the table showed her that 2 km = 2000m.

To determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

Similarly, for 8000m = 8000 / 1000 = 8 km

Answer 2

8 km

Explanation:

Write and solve an equation of ratios, as follows:

x 8000 km

--------- = -----------------

2 km 2000 m

Cross-multiplying, we get (2000 m)x = (8000 m)(2 km),

which reduces to x = 8 km
