A recipe for chocolate chip cookies calls for 1 1/4 cups of flour. If you are making 2 2/3 recipes, how many cups of flour are needed? (Simplify your answer. Type a whole number, reaction, or mixed number.)

2 2/3 cups of flour

Step-by-step explanation:

To answer this question you need to multiply 1 1/4 by 2 2/3

To multiply first make each mixed number an improper fraction

This means multiplying the whole number by the denominator, then adding the numerator

For example 1 1/4 would become 5/4 because 4 x 1 = 4 and 4 + 1 = 5, & 2 2/3 would be 8/3

Now multiply the numerator and denominator (5/4 x 8/3)

30/12 simplified to 8/3 (2 2/3)

12 pi or 37.7units

Step-by-step explanation:

the perimeter is 4 semicircles which is 2 full circles. the formula for circumference of a circle (perimeter) is diameter times pi. the diameter given is 6 so you do 6 pi times 2 full circles which is 12 pi or 37.7 units
