Final answer:
To convert the weight from pounds and ounces to kilograms, 1 pound is equal to approximately 0.4536 kilograms and 1 ounce is equal to approximately 0.02835 kilograms. Therefore, the weight of the student is approximately 45.8 kilograms.
Step-by-step explanation:
The student weighs 100 lbs 15 oz. To convert this weight to kilograms, we need to convert both pounds and ounces to kilograms separately and then add the two values together.
1 pound is equal to approximately 0.4536 kilograms, and 1 ounce is equal to approximately 0.02835 kilograms.
Therefore, the weight in kilograms is calculated as follows:
100 lbs * 0.4536 kg/lb = 45.36 kg
15 oz * 0.02835 kg/oz = 0.4253 kg
Adding the two values together:
45.36 kg + 0.4253 kg = 45.7853 kg
Rounding to the tenths place:
45.8 kg
