Show answer & explanation
Correct answer: B
Step 1: Given, width = 60 m, length = 80 m.
Step 2: Ratio of width to length = 60:80.
Step 3: Simplify the ratio by dividing both numbers by their greatest common divisor, which is 20.
Step 4: 60 ÷ 20 = 3, 80 ÷ 20 = 4. So, the simplified ratio is 3:4.
हिन्दी उत्तर:
चरण 1: दिया गया है, चौड़ाई = 60 मीटर, लंबाई = 80 मीटर।
चरण 2: चौड़ाई और लंबाई का अनुपात = 60:80।
चरण 3: दोनों संख्याओं को उनके महत्वपूर्ण सामान्य भाजक, जो 20 है, से विभाजित करके अनुपात को सरल करें।
चरण 4: 60 ÷ 20 = 3, 80 ÷ 20 = 4। इसलिए, सरलीकृत अनुपात 3:4 है।
