Answer:
30
Step-by-step explanation:
A simple way to find an unknown value in an equality with fractions is to cross-multiply:
How to cross-multiply:
1. Multiply the first numerator by the second denominator (or vise versa).
2. Multiply the second numerator by the first denominator(or vise versa).
3. Put these values into an equation, making them equal to one another.
4. Find the unknown value by solving the equation.
Now, using your problem, I will take you through the steps of cross-multiplying:
(The unknown value will be written as a variable x.)
(1.) 15 × 10 = 150
(2.) 5 × x = 5x
(3.) 5x = 150
Divide both sides of the equation by 5 to find the exact value of x.
[tex]\frac{5x}{5}[/tex] = [tex]\frac{150}{5}[/tex]
After dividing, the equation will show x = 30, which is the unknown value.
