Answer 2

10

Explanation:

Given: Isaiah puts a
`10` gram weight on a pan balance.

To Find: how many
`1` gram weights does he need to balance the scale.

Solution:

Weight on Pan Balance
`=10`
`\text{gram}`

Let number of
`1` gram weight
`=\text{x}`

To balance the scale, weight on both side of pan balance should be equal

Total weight of
`1` gram weight
`=10`
`\text{gram}`

number of
`1` gram weights,
`\text{x}=\frac{\text{Total weight}}{\text{weight of one weight}}`

`(10)/(1)`

`\text{x}=10`

Hence isaiah need
`10` weights of
`1`
`\text{gram}` to balance the scale.
