Look Ahead Grace's original rug has a length of 2 yards and a width of yard. You can write the ratio of length to width as 2 : 3. To find the unit rate, you can start with the complex fraction ? Fractions in which the numerator, the denominator, or both are also fractions are called complex fractions. 2 a. You can simplify a complex fraction by dividing. Since a fraction bar represents division, you can think of as 2 . Then you can divide to simplify. What is the unit rate for the length to width of Grace's rug? 3 b. Rewrite the complex fraction as a division expression using - c. What is the quotient of? d. Suppose a bug travelsmile in 12 minutes. Write a complex fraction you could use to find the speed of the bug in miles per minute. What is the bug's speed in miles per minute?

Part 1) The diameter is
Part 2) The radius is
Part 3) The length of an arc is equal to
Step-by-step explanation:
Part 1) Find the diameter
we know that the circumference of a circle is equal to
where
D is the diameter
we have
assume
substitute and solve for D
Part 2) Find the radius
we know that
The radius is half the diameter
so
substitute
Part 3) Find the length of an arc of 190 degrees
we know that
The circumference of the circle subtends a central angle of 360 degrees
so
using proportion
