ounce

Explanation:

Step1: Convert percentage to decimal

To find 9% of 7.5, we first convert 9% to a decimal by dividing by 100: \( 9\% = \frac{9}{100} = 0.09 \)

Step2: Multiply the decimal by the total weight

Now, we multiply this decimal by the total weight of the bar (7.5 ounces) to find the weight of the iron: \( 0.09 \times 7.5 \)

Calculating this: \( 0.09 \times 7.5 = 0.675 \)

Answer:

0.675
