Question

Lizzie played tennis for 2 2/3 hours. Andrew played tennis for 1 1/3 hours. How much longer did Lizzie play tennis than Andrew?

Answer 1

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!

Answer 2

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

$2 \frac{2}{3} -1 \frac{1}{3}$

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

$\frac{8}{3} -\frac{4}{3} = \frac{4}{3}= 1\frac{1}{3}$

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