A metal bar weighs 8.15 ounces. 93% of the bar is silver. How many ounces of silver are in the bar?
.93 * 8.15 oz = ?
93% = 93 / 100 = 0.93
93% of 8.15 ounces = 0.93 ∙ 8.15 ounces = 7.5795 ounces
approx. 7.58 ounces
To find out how many ounces of silver are in the metal bar, we need to multiply the weight of the bar by the percentage of silver.
First, let's convert 93% to decimal form by dividing it by 100:
93% ÷ 100 = 0.93
Now, multiply the weight of the bar (8.15 ounces) by 0.93 to find out how many ounces of silver are in the bar:
8.15 ounces × 0.93 = 7.5795 ounces
Rounding to the nearest hundredth, we find that there are approximately 7.58 ounces of silver in the bar.
