Answer 1

Step 1:

In this question, we are given the following:

The brooch contains 23 grams of pure silver, which is 85% of its total weight. Calculate the weight of the brooch.

Give the answer rounded to the nearest whole number.

Step 2:

The details of the solution are as follows:

`\begin{gathered} If\text{ 23 grams = 85\%} \\ \text{ x grams = 100\%} \\ crss-muliply,\text{ we have that:} \\ 85\text{ x = 100 \lparen 23\rparen} \\ 85\text{x = 2300} \\ x\text{ = }(2300)/(85) \\ \text{x =27.05882353} \\ x\text{ = 27 grams \lparen to the nearest whole number\rparen} \\ \end{gathered}`

CONCLUSION:

The final answer is:

`27\text{ grams \lparen to the nearest whole number\rparen}`
