197lb:______kg
a) 89.36kg
b) 90kg
c) 89.36kg:90.72kg
d) 90.0kg

Answer 1

After converting 197 lbs to kilograms, the weightlifter weighs 89.36 kg, which means he is light enough to compete in the class limited to those weighing 90 kg or less (a).

Step-by-step explanation:

To determine if a 197-lb weight lifter is light enough to compete in a class limited to those weighing 90 kg or less, we need to convert pounds to kilograms. Using the conversion factor 1 pound equals approximately 0.453592 kilograms, we calculate the weightlifter's mass in kilograms:

197 lb * 0.453592 kg/lb = 89.36 kg.

Therefore, the weight lifter is indeed light enough to compete in the class, as his weight in kilograms is less than 90 kg.

To convert pounds to kilograms, we need to use the conversion factor 1 lb = 0.453592 kg. Therefore, to find the weight of the weightlifter in kilograms, we can multiply 197 lb by the conversion factor:

197 lb × 0.453592 kg/lb = 89.361224 kg

So, a 197-lb weightlifter weighs approximately 89.36 kg, which is less than the limit of 90 kg. Therefore, the weightlifter is light enough to compete in the class limited to those weighing 90 kg or less.
