Answer: 1/12</h3>
Explanation:
Draw a rectangle. Then draw three vertical lines inside to split the rectangle into 4 equal pieces. Shade one of the pieces to represent 1/4.
Now draw 2 horizontal lines to split that 1/4 piece into three equal smaller pieces. You should end up with a 3 by 4 grid of small squares. There are 3*4 = 12 small squares total.
Each person gets 1/12 of a unit of ribbon, when we started off with 1/4 of a unit of ribbon. Notice how 3*(1/12) = 3/12 = 1/4.
Refer to the diagram below.
1) online has the lower unit price
27.25 / 5 = 5.45
32.16 / 6 = 5.3583333.... rounded it would be
5.35
2) The cost of 7 pounds would be 103.18
73.70 / 5 = 14.74 (cost of one pound)
14.74 x 7 = 103.18
3) The scarf in October costed more
13.35 / 3 = 4.45 (one scarf)
22.65 / 5 = 4.53
hope this helps
