Question

of 100 blocks, 12 are brown. what percent of the blocks are not brown? 88% 38% 62% 12%

Explanation:

Step1: Calculate the number of non - brown blocks

The total number of blocks is \(n = 100\), and the number of brown blocks is \(b=12\). So the number of non - brown blocks is \(100 - 12=88\).

Step2: Calculate the percentage of non - brown blocks

The formula for percentage is \(\text{Percentage}=\frac{\text{Part}}{\text{Whole}}\times100\%\). Here, the part is the number of non - brown blocks (\(88\)) and the whole is \(100\). So \(\text{Percentage}=\frac{88}{100}\times100\% = 88\%\).

Answer:

A. 88%
