Question

5B. Using the balanced seesaw shown, find the ratio of lengths a/b in lowest terms.

Answer 1

6:7

Explanation:

weight * distance = weight * distance,

so 63 * d1 = 54 * d2

LCM(63,54) = 378

378÷63 = 6

378÷54 = 7

so the answer is 6:7

Answer 2

Lowest terms is 7:6

Explanation:

A = 63

B = 54

Ratio is a:b = 63:54

63:54

Reduce 63 to lowest terms to get 7 by dividing 9.

63 ÷ 9 = 7

Reduce 54 to lowest terms to get 6 by dividing 9.

54 ÷ 9 = 6

So the reduced form 63:54 in ratio is 7:6.

7:6
