Question

A golf ball weighs around \[45.9\] grams. About how many ounces would a dozen golf balls weigh?

Answer 1

Hint: In the given question, we have been given the weight of an item. We have to find the weight of some given number of same item. To do that, we are going to multiply the weight of the item with the number of items. Then, it has also been given that we have to find the weight in another unit of measurement. To do that, we are going to use the method of conversion of one unit of measurement to another unit of measurement.

Formula used:
We are going to use the relation between ounces and grams,
\[1oz = 28.35gm\]

Complete step by step solution:
In the given question, we have been given the weight of a golf ball,
\[1\] ball \[ = 45.9gm\]
It has been given that we have to find the weight of a dozen \[\left( {12} \right)\] such balls.
So, to do that, we multiply the given relation by \[12\],
\[12\] balls \[ = 45.9 \times 12 = 550.8gm\]
We have to find the weight in ounces. So, to do that, we use the relation between ounces and grams,
\[1oz = 28.35gm\]
Now, \[\dfrac{{550.8}}{{28.35}} = 19.42\]
So, multiplying the relation between ounces and grams by \[19.42\],
Weight of a dozen golf balls \[ = 19.42oz\]

Note: In the given question we had been given the weight of an item. We had to find the weight of a given number of the same such items. To do that, we multiplied the weight of the item with the number of items. Then, we had to find the weight in another unit of measurement. To do that, we used the method of conversion of one unit of measurement to another unit of measurement. And that gave us the answer. So, it is important that we know the correct way of doing the questions.
