Answer:
Her weight three month ago was 2.24 kg
Step-by-step explanation:
This is because it was stated that , newborns increase in weight by 60% for the first 3 months of their lives. Therefore, we calculate 60% of her weight now and subtract it from her weight now to get her weight 3 months ago
60% of 5.6 kg = 3.36 kg
therefore, 5.6 - 3.36 = 2.24kg
