Answer 1

Answer:

Carlos rode further on Sunday by $1\frac{51}{56} miles$ miles.

Step-by-step explanation:

Carlos covered distance on Saturday $=\frac{139}{8}$

He covered distance on Sunday = $\frac{135}{7}$

Equivalent fractions:

$\frac{139}{8} \times \frac{7}{7}=\frac{973}{56}\\ \frac{135}{7} \times \frac{8}{8}=\frac{1080}{56}$

So,$\frac{1080}{56}>\frac{973}{56}\\ \frac{135}{7}>\frac{139}{8}$

So, He covered more distance on Sunday

Difference between distances =$\frac{1080}{56}-\frac{973}{56}=\frac{107}{56}=1\frac{51}{56}$

So, Carlos rode further on Sunday by $1\frac{51}{56} miles$ miles.
