Q: In a parliamentary election, if 40% of the votes are invalid and 60% are valid, what is the ratio of valid votes to total votes if there are 1000 total votes? (2019)
Solution: Valid votes = 60% of 1000 = 600. Total votes = 1000. Ratio = 600:1000 = 3:5.
Steps: 9
Step 1: Understand that there are 1000 total votes.
Step 2: Calculate the number of valid votes by finding 60% of 1000.
Step 3: To find 60% of 1000, multiply 1000 by 0.6 (which is the decimal form of 60%).
Step 4: 1000 * 0.6 = 600. So, there are 600 valid votes.
Step 5: The total number of votes is still 1000.
Step 6: Now, we need to find the ratio of valid votes to total votes, which is 600 to 1000.
Step 7: To simplify the ratio 600:1000, divide both numbers by 200.
Step 8: 600 ÷ 200 = 3 and 1000 ÷ 200 = 5.
Step 9: Therefore, the simplified ratio of valid votes to total votes is 3:5.
