My question is: Barbi lost 1.5 kilograms each month for a year. Luca lost 9 kilograms every year for 11 years. How many more kilograms did Luca lose than Barbi? Your thoughts:
Barbi = 1.5 * 12 months = 18 kg. Luca = 9 * 11 = 99 kg. 99 - 18 = 81 kg. Luca lost 81 kg more than Barbi. The final answer: 81.
