Question 5 Pairs of quantities are shown below. Identify and write appropriate symbols ‘>’, ‘<’, ‘=’ in the blanks. Try to do it without calculations. (i) 50% ____ 5%Since both are in percentages, we just compare the numbers Since 50 > 5, Thus, 50% > 5% Question 5 Pairs of quantities are shown below. Identify and write appropriate symbols ‘>’, ‘<’, ‘=’ in the blanks. Try to do it without calculations. (ii) 5/1 ____ 50%We convert 5/1 into percentage Now, 𝟓/𝟏=5/1 × 100% =5 × 100% =𝟓𝟎𝟎% So, our question becomes 500% ____ 50% Since both are in percentages, we just compare the numbers Since 500 > 50, Thus, 500% > 50% Or 𝟓/𝟏 > 50% Question 5 Pairs of quantities are shown below. Identify and write appropriate symbols ‘>’, ‘<’, ‘=’ in the blanks. Try to do it without calculations. (iii) 3/11 _____ 61%We convert 3/11 into percentage Now, 𝟑/𝟏𝟏=3/11 × 100% =300/11% =𝟐𝟕.𝟐𝟕…% So, our question becomes 27.27…% ____ 61% Since both are in percentages, we just compare the numbers Since 27.27… < 61, Thus, 27.27…% < 61% Or 𝟑/𝟏𝟏 < 61% Question 5 Pairs of quantities are shown below. Identify and write appropriate symbols ‘>’, ‘<’, ‘=’ in the blanks. Try to do it without calculations. (iv) 30% ____ 1/3We convert 1/3 into percentage Now, 𝟏/𝟑=1/3 × 100% =100/3% =𝟑𝟑.𝟑𝟑…% So, our question becomes 30 % ____ 33.33…% Since both are in percentages, we just compare the numbers Since 30 < 33.33…, Thus, 30% < 33.33…% Or 30% < 𝟏/𝟑
