Calculating the Weight of an Ingredient When the Weight of Flour is Known

Divide the percentage value of the ingredient by 100 to get its decimal version, then multiply by the weight of the flour.

Decimal value of ingredient X Total weight of flour = Total weight of ingredient

A bread formula lists the ingredient values only in percentages. You want to make a batch of dough using 5 lb flour. You need to calculate the weight for the raisins, which are valued at 60 percent, so you can prep them for making the dough the next day.
