Answer:
9 inches.
Explanation:
To find out what d (distance) is, make a proportion of the values you know and d. This would be 15/67.5 = 2/d.
¹⁵/₆₇.₅ = 2/d
Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by d.
d * (¹⁵/₆₇.₅) = 2
Expand 15/67.5 by multiplying both numerator and the denominator by 10.
d * (¹⁵⁰/₆₇₅) = 2
Reduce the fraction ¹⁵⁰/₆₇₅ to lowest terms by extracting and canceling out 75.
d * (²/₉) = 2
Multiply both sides by ⁹/₂, the reciprocal of ²/₉.
d = (2 * 9)/2
Cancel out 2 and 2.
d = 9
The distance between the SLMS from the tide pools on the map is 9 inches.
