Erika has 3 pieces of ribbon. each piece is 25 yards long she needs to cut pieces that are 22 inches long . what is the greatest number of 22-inch pieces that she can cut from the three ribbons ?

So 1 yard=3 feet
1 feet=12 inches
1 yard=3 times 12 inches=36 inches

she has 3 pieces of ribbon each is 25 yards long

total inches=3 times 25 times 36=2700

how many 22's are in 2700
divide
2700/22 and round down
122.7
you can't have 0.7 of a 22 inch piece so round down to 122

the nasewr is 122 pieces
