the answer is 54
A proportion states that two ratios are equal. In this case, we have:
48 / x = 8 / 9
To solve for x, we can cross multiply:
48 * 9 = 8 * ×
Simplifying the equation:
432 = 8x
Divide both sides by 8 to isolate x:
× = 432 / 8
× = 54
Therefore, the missing number in the ratio 48:
_= 8:9 is 54.
