Lets get started :)
We can use the
concept of ratios 5g of margarine : 3.6g fats
92g of margarine : ?
We can cross multiply, which is an easier solution
Let us use the variable
p to represent the
grams of fats to be found
5 x p = 3.6 x 92
5p = 331.2
We, now, can divide by 5 on either sides so we can isolate and find the value of p

5 and 5 cancels out
p = 66.24
So, 92g of margarine will contain 66.24g of fats
