solve the proportion
x/12=91/84
A)6
B)8
C)13
D)3
Cross multiply. Solve for x
x/12=91/84
84x = 1092
x = ?
1092 divided by 84 doesn't equal 6.
b that is so easy
To solve the proportion x/12 = 91/84, you can cross-multiply and then solve for x.
Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction, and vice versa. In this case, you would multiply x with 84, and 12 with 91. It can be represented as:
x * 84 = 12 * 91
Now, let's solve this equation step by step:
84x = 1092 (multiplied 12 and 91)
Divide both sides by 84 to isolate x:
84x/84 = 1092/84
x = 13 (simplified)
So, the value of x is 13.
Therefore, the answer is option C) 13.
