Solve the proportion using cross products.
Start Fraction 18 over 20 End Fraction equals Start Fraction k over 110 End Fraction
To solve the proportion using cross products, we need to find the product of the numerator of the first fraction and the denominator of the second fraction, and then set it equal to the product of the denominator of the first fraction and the numerator of the second fraction.
18 * 110 = 20 * k
1980 = 20k
To solve for k, we need to divide both sides of the equation by 20:
1980/20 = k
99 = k
Therefore, k is equal to 99.
To solve the proportion using cross products, we can use the formula:
(ad = bc)
Given the proportion:
Start Fraction 18 over 20 End Fraction equals Start Fraction k over 110 End Fraction
We can set up the equation as follows:
(18 * 110 = 20 * k)
Now, we can solve for k:
1980 = 20k
To isolate k, divide both sides of the equation by 20:
1980/20 = k
Simplifying the equation:
99 = k
Therefore, the value of k is 99.
