### Practice problem 1

This is a rectangle.
Let's measure the start color #11accd, start text, b, l, u, e, space, l, i, n, e, end text, end color #11accd below using both rectangles and a centimeter ruler:
The line is
rectangles long.

The line is
centimeters long.

The width of each rectangle is _____ than a centimeter.

So, it takes _____ rectangles than centimeters to measure the line.

### Practice problem 2

Measure the start color #1fab54, start text, g, r, e, e, n, space, l, i, n, e, end text, end color #1fab54 using the centimeter ruler.
The line is
centimeters long.

Now, measure the start color #1fab54, start text, g, r, e, e, n, space, l, i, n, e, end text, end color #1fab54 using the inch ruler.
The line is
