You are lubricating several motors in the shop. One motor must be lubricated with \( \frac{3}{16} \) of an ounce of grease "and one larger motor must be lubricated with \( \frac{3}{8} \) of an ounce of grease. How many ounces of grease will you require? Your answer should be a fraction of an ounce, reduced to its lowest terms. You need \( \square \) of an ounce [of grease.

To find the total amount of grease needed, you simply need to add the two fractions: \( \frac{3}{16} \) and \( \frac{3}{8} \). First, convert \( \frac{3}{8} \) to sixteenths by multiplying both the numerator and the denominator by 2, giving you \( \frac{6}{16} \). Now, add \( \frac{3}{16} + \frac{6}{16} = \frac{9}{16} \). So, you will require \( \frac{9}{16} \) of an ounce of grease. Now that you have your total figured out, remember that maintaining the right lubrication for motors is crucial in prolonging their lifespan and improving efficiency. Regular lubrication, just like giving your car an oil change, helps prevent overheating and reduces the wear of moving parts. Make sure to check the manufacturer's guidelines for the right lubrication intervals!
