To find the change in Claire's weight, you subtract her weight in March from her weight in September.
September weight: 187.4 pounds
March weight: 163.5 pounds
Change in weight = September weight - March weight
Change in weight = 187.4 - 163.5
Now, performing the subtraction:
187.4 - 163.5 = 23.9
So, the rational number that represents the change in Claire’s weight is 23.9.
Yes, the calculation is correct.
To confirm:
To find the change in weight:
\[ \text{Change in weight} = \text{September weight} - \text{March weight} \] \[ \text{Change in weight} = 187.4 - 163.5 = 23.9 \text{ pounds} \]
Thus, the change in Claire's weight is indeed 23.9 pounds.
