Answer:
1.3 inches
Step-by-step explanation:
1. Determine what you already know in order to set up the equation:
1 inch = 100 miles
<em>x</em> inches = 130 miles
Solving for <em>x</em>
2. Set up the equation so both numerators are the same unit (In this case, both numerators are the mile values and both denominators are the inch values.)
=
3. Cross multiply (Multiply the first fraction's numerator by the second fraction's denominator, and vice versa. It doesn't matter which number is on which side of the = sign.)
100<em>x</em> = 130
4. Divide each side by 100 to isolate the variable.
<em>x</em> = 1.3
