a/b = c/d
What is your question?
how do I solve the problem?
Is it possible to solve that with different variables?
The equation you mentioned, a/b = c/d, is a proportion. It states that the ratio of a to b is equal to the ratio of c to d.
To solve this proportion, you can use what is called the cross-multiplication method. Here are the steps:
1. Start by cross-multiplying. Multiply a by d and multiply b by c.
(a * d) = (b * c)
2. Set up an equation with the cross-products.
ad = bc
3. Solve the equation for the unknown variable.
If you want to solve for a, you divide both sides of the equation by d:
a = (bc) / d
If you want to solve for b, you divide both sides of the equation by c:
b = (ad) / c
If you want to solve for c, you divide both sides of the equation by b:
c = (ad) / b
If you want to solve for d, you divide both sides of the equation by a:
d = (bc) / a
By following these steps, you can find the value of any variable in the proportion a/b = c/d.
