Question

Jordan is$6feet$tall and weighs $51.4kg$. Porter is$6feet$ tall and weighs $42000g$Who is heavier and by how much?

Answer 1

Step 1. Make unit of weights equal.

$42000g=\frac{42000}{1000}kg=42kg(1g=\frac{1}{1000}kg)$

So, the weight of Jordan is $51.4kg$ and that of Porter is $42kg$.

Step 2. Compare the given weights.

Clearly, we can see that $51.4kg>42kg$.

Therefore, Jordan is heavy than Porter.

Step 3. Subtract $42.0kg$ from $51.4kg$, to get difference of their weights.

$$\begin{gathered} 51.4kg \\ -42.0kg \\ \_\_\_\_\_\_\_\_ \\ 9.4kg \end{gathered}$$

Hence, Jordan is heavy by $9.4kg$.
