Question

Solve for w, b, and r using the proportions from part A. Show your work.

White strands: w/80 = 35/100

Blue strands: b/80 = 25/100

Red strands: r/80 = 40/100

Answer 1

Step-by-step explanation:

Given Solve for w, b, and r using the proportions from part A.   Show your work.

White strands: w/80 = 35/100

Blue strands: b/80 = 25/100

Red strands: r/80 = 40/100

• We need to solve the proportion for white strands w, blue strands b and red strands r. So we have the proportions as follows.
• So w/80 = 35 / 100
• Or w : 80 : : 35 : 100
• So property of means is equal to property of extremes.
• So 100 x w = 35 x 80
• Or w = 35 x 80 / 100
• Or w = 7
• Now for blue strands we have
•   So b/80 = 25/100
•   So b: 80 : : 25 : 100
•   Or 100 x b = 80 x 25
•    Or b = 80 x 25 / 100
•    Or b = 20
• Now for the red strands we have
•   So r/80 = 40/100
•  So r:80 : : 40 : 100
•   So 100 x r = 40 x 80
•    Or r = 40 x 80 / 100
•    Or r = 32
• So w = 7, b = 20 and r = 32
