I hope this helps! :)
To solve the proportion 27/90 = 3/?, you can cross-multiply and then solve for the missing value.
Cross-multiplying gives us: 27 * ? = 90 * 3
Simplifying, we have: ? = (90 * 3) / 27
Calculating, we get: ? = 270 / 27 = 10
So, the answer is B.
To solve the proportion, we can cross multiply.
First, let's write the proportion as an equation:
27/90 = 3/x
Cross multiplying means multiplying the numerator of the first fraction by the denominator of the second fraction, and then multiplying the denominator of the first fraction by the numerator of the second fraction.
27 * x = 90 * 3
27x = 270
To solve for x, we divide both sides of the equation by 27:
x = 270/27
Simplifying, we get:
x = 10
So the value of x that satisfies the proportion is 10.
Therefore, the correct answer is B.
