Answer:
Query: After losing 2 1/2 kilograms in each of the first 2 weeks of March and gaining 1 3/8 kilograms in each of the next 2 weeks, Mang Ambo's piglet weighed 110 kilograms. How much did his piglet weigh on March 1?
Result:
To find out how much Mang Ambo's piglet weighed on March 1st, we can work backwards from the final weight of 110 kilograms.
1. In the first 2 weeks of March, the piglet lost 2 1/2 kilograms each week. So, in total, it lost 2 1/2 + 2 1/2 = 5 kilograms.
2. In the next 2 weeks, the piglet gained 1 3/8 kilograms each week. So, in total, it gained 1 3/8 + 1 3/8 = 2 6/8 kilograms, which simplifies to 2 3/4 kilograms.
Therefore, the net change in weight over the 4 weeks was a loss of 5 kilograms followed by a gain of 2 3/4 kilograms, resulting in a net loss of 5 - 2 3/4 = 2 1/4 kilograms.
If the piglet's weight ended up at 110 kilograms, and it lost 2 1/4 kilograms over the 4 weeks, then its weight on March 1st would have been:
110 kg + 2 1/4 kg = 112 1/4 kg
Therefore, Mang Ambo's piglet weighed 112 1/4 kilograms on March 1st.
