Question

what percent of 400m is 1km​

Answer 1

Answer:

40%

Explanation:

1000 m will be 100% of 1km

Answer 2

Answer:

1 km is 250 per cent of 400m

Explanation:

If "a" and "b" are two entities. Then,

"a" as a % of b = (a/b)*100

1 km = 1000m

1000m as % of 400m = (1000/400)*100 = (10/4)*100 = 1000/4 = 250%

In case the question is "what per cent of 1 km is 400m?" then the answer would be:

(400/1000)*100 = 40%
