MP Board · Class 7 · Mathematics · Comparing QuantitiesFind the ratio of 3 km to 300 m.
Step-by-Step Solution
To find the ratio, both quantities must be in the same units. We know that 1 km = 1000 m. Therefore, 3 km = 3 × 1000 = 3000 m. The ratio of 3000 m to 300 m is 3000 : 300. Simplifying this, 3000 ÷ 300 = 10 and 300 ÷ 300 = 1, so the ratio is 10 : 1.
