Question

will you kindly assist me pls. work math step by step answer in numbers pls. to work how you got the answer

Answer 1

Translating for numbers, we have:

$\frac{1}{5}=0,2\rightarrow3\frac{1}{5}=3,2$

This way, we can make what follows:

$Day_1+Day_2=3\frac{1}{5}+4=3,2+4=7,2_{}$

Calculating now the amount is needed to complete the 9 miles:

$Day_3=9-7,2\text{ = 1,8}$

--------------------------------------------------------------------------------------------------------

And from here, the solution with the fractions.

We can start with the sum of what Shelly has biked in the first two days:

$Day_1+Day_2=3\frac{1}{5}+4=7\frac{1}{5}_{}$

This is the amount of mile she has already biked. But we know she needs to complete all the 9 miles in the third day. So, the difference from 9 and the amount she already did is the amount she needs to bike in the third day.

$\text{Day}_3\text{ = 9 - 7}\frac{1}{5}\text{ = 1}\frac{4}{5}$
