Question

The table shows the weights of bananas at a grocery store. Complete the table so that there is a proportional relationship between the number of bananas and their weight.Number Of Bananas. Weight In Kilograms. 2 ? 0.72 15 ?

Answer 1

Let u make the first box x and the second box y.

If there is a proportional relationship between the number of bananas and their weights, it means that:

`(2)/(x)=(6)/(0.72)=(15)/(y)`

We can take the first pair and solve for x as follows:

`\begin{gathered} (2)/(x)=(6)/(0.72) \\ 6x=2*0.72=1.44 \\ x=(1.44)/(6) \\ x=0.24 \end{gathered}`

We can solve for y in the same manner:

`\begin{gathered} (6)/(0.72)=(15)/(y) \\ 6y=15*0.72=10.8 \\ y=(10.8)/(6) \\ y=1.8 \end{gathered}`

Therefore, the boxes are filled as shown below:
