Question

The most a bowling ball can weigh is 7,258 grams. What is the most it can weigh when measured in pounds?

Answer 1

Hint: Here we just need to convert the unit from grams to pounds. So to do this, we know that \[1kg = 2.20462pounds\] and \[1kg = 1000gm\]. By using this we will convert the gram to kg first then we will convert it to pounds.

Complete step-by-step answer:
Given that, the weight of the bowling ball is
\[ \Rightarrow 7258 g\]
Where, g denotes grams.
Since we know that,
\[ \Rightarrow 1000g = 1kg\]
Where, kg denotes kilograms.
Therefore, we can convert the weight of the bowling ball from grams into kilograms by dividing the weight of the bowling ball in grams by 1000 grams.
So we can write,
\[ \Rightarrow 7258g = \dfrac{{7258}}{{1000}}kg\]
That gives,
\[ \Rightarrow 7258g = 7.258kg\]
Therefore, the weight of the bowling ball is 7.258 kilograms.
Now we need to convert the weight of the bowling ball from kilograms to pounds.
Since we know that,
\[ \Rightarrow 1kg = 2.20462pounds\]
Therefore, by multiplying the weight in kilograms to the conversion rate in pounds will give us the required weight in pounds.
So, we can write
\[ \Rightarrow 7.258kg = 7.258 \times 2.20462pounds\]
Calculating the RHS gives us,
\[ \Rightarrow 7.258kg = 16.001pounds\]
Approximately, we can write
\[ \Rightarrow 7.258kg = 16pounds\]
Therefore, the bowling ball can weigh at most, when measured in pounds is 16 pounds.

Note: Weight or mass can be measured in different measuring units. However, the S.I. unit of measuring weight is grams. But it is measured in different units at different places. Some other units of measuring weight are kilograms, milligrams, tonnes, pounds, ounces, stones, etc. Therefore different conversion rates are needed in order to calculate a weight in the required units.
Some of the most common conversion rates are:
\[ \Rightarrow 1kg = 1000g\]
\[ \Rightarrow 1000mg = 1g\]
\[ \Rightarrow 1000kg = 1tonne\]
\[ \Rightarrow 1kg = 2.20462pounds\]
