Inessa [10]
To find the miles for 3rd day, we take away the miles she biked for the first two day from the total.

   50 - 17 \dfrac{7}{8} - 18\dfrac{5}{7}

=50 - 17 \dfrac{7 \times 7}{8 \times 7} - 18\dfrac{5 \times 8}{7 \times 8}

= 48 \dfrac{112}{56}  - 17 \dfrac{49}{56} - 18\dfrac{40}{56}

= 13 \dfrac{23}{56}   \text { miles }

The ratio of the number of Sam's CDs to the number of Alice's CD's is 7 to 8. Sam has 84 CDS.
Alex

Answer:

180 CDs

Step-by-step explanation:

So if Sam has 84 CDs, and the ratio from Sam to Alice is 7:8, we can do 84/7=12 so each number is equal to 12. Then we add up 7 and 8 and get 15, so we do 15*12 and we get 180.
