m = 4
Expiation
To solve the proportion 9:6 = 6:m for m, we can use cross-multiplication. Cross-multiplication involves multiplying the numerator of one side of the equation by the denominator of the other side, and then setting the two resulting products equal to each other. We get:
9 × m = 6 × 6
Multiplying the terms on the right-hand side, we have:
9m = 36
Dividing both sides by 9, we get:
m = 4
Therefore, the value of m is 4.
