A trail mix contains a 4: 7 ratio of raisins to peanuts. How many kilograms of raisins are there if there are four kilograms of peanuts in the mix?
4/7 = x/4
Cross multiply and solve for x
To find the number of kilograms of raisins in the mix, we need to use the given ratio of raisins to peanuts.
First, let's set up a proportion based on the ratio:
4 (kg of peanuts) / 7 (kg of raisins) = 4 (kg of peanuts from the ratio) / x (kg of raisins that we want to find)
Next, we can cross-multiply and solve for x:
4 * x = 7 * 4
4x = 28
Now, divide both sides of the equation by 4 to isolate x:
x = 28 / 4
x = 7
So, there are 7 kilograms of raisins in the trail mix.
