Answer:
[tex]\frac{9}{14}[/tex] km
Step-by-step explanation:
We are given that
Eric ran on Wednesday=[tex]\frac{9}{10}[/tex] km
Eric ran on Friday=[tex]1\frac{1}{2}[/tex]=[tex]\frac{3}{2} km[/tex]
We have to find how much distance ran by Eric on Monday.
Eric ran on Monday=[tex]\frac{5}{7}[/tex] of the distance that he ran on Wednesday.
To find the [tex]\frac{5}{7}[/tex] part of the distance ran on Wednesday we will multiply [tex]\frac{5}{7}[/tex] by [tex]\frac{9}{10}[/tex]
[tex]\frac{5}{7}\times \frac{9}{10}=\frac{1}{7}\times \frac{9}{2} km[/tex]
[tex]=\frac{9}{14}[/tex] km
Eric ran on Monday=[tex]\frac{9}{14}[/tex] km
Hence, Eric ran on Monday=[tex]\frac{9}{14}[/tex] km
