J) 700 is 10% of what number? square

## Step 1: Identify the Given Values<br />### We know that $700$ is $10\%$ of some unknown number, which we will call $x$.<br />## Step 2: Set Up the Equation<br />### The equation for finding a percentage of a number is given by: $\text{part} = \frac{\text{percentage}}{100} \times \text{whole}$. Here, $700 = \frac{10}{100} \times x$.<br />## Step 3: Solve for the Unknown<br />### Rearrange the equation to solve for $x$: <br />\[ <br />700 = \frac{10}{100} \times x <br />\]<br />\[ <br />700 = 0.1 \times x <br />\]<br />\[ <br />x = \frac{700}{0.1} <br />\]<br />\[ <br />x = 7000 <br />\]
