1. State the problem. Daniela made gift bows from 8 yards of ribbon and she made 16 bows. How much ribbon did she use for each bow? 2. Formula and rules. We use the formula to find the amount per item by dividing the total quantity by the number of items. $$\text{ribbon per bow} = \frac{\text{total ribbon}}{\text{number of bows}}$$ Important rule: When dividing equally, split the total evenly so each item gets the quotient. 3. Calculation and intermediate work. Substitute the given numbers into the formula: $$\frac{8}{16}$$ Now simplify the fraction by canceling common factors and show the cancellation: $$\frac{\cancel{8}}{\cancel{16}} = \frac{1}{2}$$ So the amount per bow is $\frac{1}{2}$ yard. 4. Final answer. Each bow used $\frac{1}{2}$ yard of ribbon.
