Question

Can someone explain how the answer to #14 is 7/8 in;0.875 in.

Answer 1

Of the 16 small intervals indicated from 0 to 1 inch, the ant spans 14 of them, so

`(14)/(16) = (7)/(8) \textrm{ inches} = 0.875 \textrm{ in}`

How is 7/8 equal to 0.875?

Since 125(8)=1000 and 125(7)=875 we know

`(7)/(8) = (7 \cdot 125)/(8 \cdot 125) = (875)/(1000) = 0.875`
