To write a percent that compares the size of the large milkshake to the size of the small milkshake, we can first establish that the large milkshake is 1.4 times the size of the medium milkshake. Now, if we assume that the small milkshake is the same size as the medium milkshake, we can express the comparison as a percentage increase from small to large.
Percentage increase = [(Large size - Small size) / Small size] x 100
In this case, Large size is 1.4 times the Small size (or 1.4 times the Medium size, which is the same as Small size). So,
Percentage increase = [(1.4 * Small size - Small size) / Small size] x 100
Now, let's calculate it:
Percentage increase = [(1.4 - 1) * 100]%
Percentage increase = (0.4 * 100)%
Percentage increase = 40%
So, the large milkshake is 40% larger than the small milkshake.
Now, I can't draw or shade grids directly as text, but I can describe how you can create a 10x10 grid to model this visually:
1. Draw a 10x10 grid on a piece of paper, whiteboard, or a digital drawing tool. This grid represents the size of the small milkshake.
2. Shade 40% of the squares in the grid. This represents the additional size of the large milkshake compared to the small milkshake.
3. Count the number of shaded squares. You should have 40 out of the 100 squares shaded, which visually represents the 40% increase in size.
This grid model visually illustrates that the large milkshake is 40% larger than the small milkshake.
