I cut 4 blue strips of paper, EACH measuring 7/12 inch wide. I lay these strips side by side.
I also cut 3 yellow strips of paper. When I lay the 3 yellow strips next to each other, their TOTAL width is 9/12 inch.
The difference between the total width of the blue strips and the total width of the yellow strips is _______.
What is 19/12 inch ?
