To solve the equation 3: ____ = 48:80, we can utilize the concept of ratio.
In a ratio, the two numbers on each side of the colon (:) represent corresponding parts. To find the missing value in the equation, we need to determine what number can be substituted in place of the blank to make the left side of the ratio equal to the right side.
In the given equation, we have the ratio 3:x = 48:80.
To solve for x, we can set up a proportion by cross-multiplying. This means multiplying the numerator of the first ratio (3) by the denominator of the second ratio (80) and the denominator of the first ratio (x) by the numerator of the second ratio (48). The equation would be:
3 * 80 = x * 48
240 = 48x
To isolate x, we can divide both sides of the equation by 48:
240/48 = x
5 = x
Therefore, the solution to the equation is x = 5.
