72+7,2=79,2кг-в январе
в феврале: 79,2+17,2=96,4кг
96,4:72*100%=133,8%≈134%

Answer 2

Calculation of Georgiy's Weight in February

To determine the percentage of Georgiy's weight in February compared to his weight in December, we need to calculate his weight in February and then calculate the percentage difference.

Given the information provided: - Georgiy weighed 72 kg in December. - In January, he gained 10% more weight. - In February, he gained an additional 18 kg.

To calculate Georgiy's weight in January, we can add 10% of his weight in December to his December weight: - Weight in January = 72 kg + (10% of 72 kg) = 72 kg + (0.1 * 72 kg) = 72 kg + 7.2 kg = 79.2 kg.

To calculate Georgiy's weight in February, we can add the weight he gained in February to his weight in January: - Weight in February = 79.2 kg + 18 kg = 97.2 kg.

Now, let's calculate the percentage of Georgiy's weight in February compared to his weight in December:

Step 1: Calculate the difference between Georgiy's weight in February and his weight in December: - Weight difference = Weight in February - Weight in December = 97.2 kg - 72 kg = 25.2 kg.

Step 2: Calculate the percentage difference: - Percentage difference = (Weight difference / Weight in December) * 100 = (25.2 kg / 72 kg) * 100 ≈ 35%.

Therefore, Georgiy's weight in February represents approximately 35% of his weight in December.
