Answer 1

To find the change in Claire's weight, you need to subtract her weight in March from her weight in September:

\[ \text{Change in weight} = \text{Weight in September} - \text{Weight in March} \]

Substituting the given values:

\[ \text{Change in weight} = 187.4 , \text{pounds} - 163.5 , \text{pounds} \]

Calculating the difference:

\[ \text{Change in weight} = 187.4 - 163.5 = 23.9 , \text{pounds} \]

The rational number that represents the change in Claire’s weight is:

\[ \boxed{23.9} \]
