Respuesta :

Andrew played for 1 hour and 20 minutes
Lizzie played for 2 hours and 40 minutes
Andrew played for half as long as Lizzie did, so Lizzie played for 1 1/3 hours longer than Andrew did. Hope this helps!

You have to subtract Andrew's playing time from Lizzie's:

[tex]2 \frac{2}{3} -1 \frac{1}{3} [/tex]

For simpler subtraction, we can convert the mixed numbers into improper fractions:

[tex]\frac{8}{3} -\frac{4}{3} = \frac{4}{3}= 1\frac{1}{3} [/tex]

Lizzie played tennis [tex]1\frac{1}{3}[/tex] hours, or 1 hour and 20 minutes, longer than Andrew.
