Question

Josiah has taken up running as a new hobby . He lost 5 7/10 pounds over 3 weeks. if his starting weight was 187.2 pounds, what does he weight now?

Answer 1

To find what does Josiah weight now, solve the difference between 187.2 and 5 7/10.

To do this the first step is to convert the mixed number into a fraction and then into a decimal number. This will make things easier to us at the moment of solving the difference.

$5\frac{7}{10}=\frac{50}{10}+\frac{7}{10}=\frac{57}{10}=5.7$

Finally, solve 187.2 minus 5.7

$187.2-5.7=181.5$

Josiah weights 181.5 pounds now.
