Josefina needs enough ribbon to make 90 bookmarks. Each bookmark is to be 5 and 7/9 inches long. Estimate how many yards of ribbon she should buy.

(5+7/9)*90

450 + 70

520 inches ; divide by 36
Buy 15 yards.

(5+7/9)*90

450 + 70

520 inches ; divide by 36
Buy 15 yards.

Why would you add 5+7/9?

O i get that now... but 520/36=14 and 4/9... wouldn't that round to just 14 because 4/9= .44444444444...

O i get that now 2... u would need 15 just 2 hav enough... Thank u SO MUCH Mr Pursley... Sorry 4 all da trouble
