✅ ANSWER KEY – SET 1
I. Choose the correct option
- (a) 0.569
- (c) Less than both numbers
- (c) 0.036
- (a) 16.45 pages
- (b) 26.5625
II. Solve the following
Distance = 0.75 × 12 = 9 km
Product is greater than both numbers (both numbers are greater than 1 or one is greater than 1, so product increases).
300 g = 0.3 kg
150 g = 0.15 kg
250 g = 0.25 kg
Total weight = 0.3 + 0.15 + 0.25 = 0.7 kg
Total cost = 0.7 × 180 = ₹126
(a) 6.5 × 1.2 = 7.8 km
(b) 7.8 is greater than 6.5 and 1.2
(c) Since both numbers are greater than 1, the product is greater than both.
Milk cost = 4 × 54.75 = ₹219.00
Juice cost = 3 × 68.40 = ₹205.20
Total = 219 + 205.20 = ₹424.20
Other number = 3.375 ÷ 15 = 0.225
Area = 7.2 × 4.5 = 32.4 sq. m
Number of sides = 21.6 ÷ 3.6 = 6 sides
III. Case Study
(a) 0.8 × 65 = 52 g
(b) 56 ÷ 0.8 = 70 kg
(c) 325.75 × 6 = ₹1954.50
(d) 2500 − 1954.50 = ₹545.50
(e) 325.75 × 10 = ₹3257.50
