Question

holly is displaying a postcard collection on a bulletin board that is 35 3/4 inches Wide. Each post card is 5 7/8 inches wide. Holly estimates that the number of postcards she can display in each row is 7. Is this the best estimate? Explain

Answer 1

No, it is not.

Explanation:

The bulletin board is

`35(3)/(4)=(35.4+3)/(4)=(143)/(4)=35.75` inches wide

Each postcard is

`5(7)/(8)=(40+7)/(8)=(47)/(8)=5.875` inches wide

So, the maximum number of postcards than can be displayed in a row is

`(37.75)/(5.875)=6.085\approx 6`

So, the best estimate is 6 postcards per row.
