A sidewalk along side a garden at the Conservatory is to be 11 4/9 yards long. Rectangular stone tiles that are each 2 1/18 yard long are used to fall in the sidewalk. How many tiles were used?

Step-by-step explanation:

Convert the fractions in the yards given to decimals, because then you can divide the length of the sidewalk by the length of each tile. So 2/5 is 2 divided by 5 which equals .4. And 1/8 is 1 divided by 8 which is .125.

So, the sidewalk is 14.4 yards long and each tile is 1.125 yards long.

Divide the length of the sidewalk, 14.4 yards, by the length of each tile, 1.125 yards.

Equals 13.8 tiles, rounded off to 14 tiles.

Hope this helps.

14 2/5 = 72/5

1 1/8 = 9/8

72/5 = 576/40 divide by 45/40 = 576/40 x 40/45 = 23040/1800 = 12.8 tiles
