You know that to make 20 pancakes you have to use 2 eggs. How many eggs are needed to make 100 pancakes?
If we write the unknown number in the nominator then we can solve this as any other equation
If we write the unknown number in the nominator then we can solve this as any other equationx100=220x100=220
If we write the unknown number in the nominator then we can solve this as any other equationx100=220x100=220Multiply both sides with 100
If we write the unknown number in the nominator then we can solve this as any other equationx100=220x100=220Multiply both sides with 100100⋅x100=100⋅220100⋅x100=100⋅220
If we write the unknown number in the nominator then we can solve this as any other equationx100=220x100=220Multiply both sides with 100100⋅x100=100⋅220100⋅x100=100⋅220x=20020x=20020

If we write the unknown number in the nominator then we can solve this as any other equationx100=220x100=220Multiply both sides with 100100⋅x100=100⋅220100⋅x100=100⋅220x=20020x=20020x=10x=10If the unknown number is in the denominator we can use another method that involves the cross product. The cross product is the product of the numerator of one of the ratios and the denominator of the second ratio. The cross products of a proportion is always equal
