Juliana had 15 1/2 inches of green ribbon for an art project. She cut off one piece of ribbon that was 2 3/4 inches long and another piece that was 6 2/3 inches long. How many inches of ribbon did she have left?
[15 + 1/2 ] - [ 2 + 3/4 ] - [6 + 2/3 ]......convertng these to improper fractions, we have
[31 /2 ] - [11 / 4 ] - [ 20 / 3 ] getting a common denominator (12), we have
[186 / 12] - [33 / 12 ] - [ 80 / 12 ] = 73 / 12 inches = about 6.0833 inches left
