I assume that the length of the rectangle is 8 inch more than width .
Answer:
7/3
Step-by-step explanation:
Let the two numbers be x and y which are relatively prime to each other.
a/b = 5/2
So you want the ratio of
(a + b) / (a - b)
- Take out a common factor of b
- numerator: b(a/b + 1)
- denominator: b(a/b - 1)
- Put them together
- The b's cancel out
- (a/b + 1) / (a/b - 1)
- but a/b = 5/2
- (5/2 + 1) / (5/2 - 1)
- Numerator: (5/2 + 2/2) = 7/2
- Denominator: 5/2 - 2/2 = 3/2
- numerator over denominator = 7/2 // 3/2 = 7/2 * 2/3 = 7/3
Answer: 7/3
Nice problem: Thanks for posting.
3+4 = 7
so
21 / 7 3
3 x 3 = 9
3 x 4 = 12
answer
£21 in ratio 3:4 is £9:£12
