Fraction subtraction worksheet for tape measurement practice.

Here are the step-by-step solutions for each problem on the worksheet. To subtract fractions, we first need to make sure the bottom numbers (denominators) are the same. If they aren't, we change one or both fractions so they match. Then, we just subtract the top numbers.

1) $\frac{5}{8} - \frac{7}{16}$
* The denominators are 8 and 16. Since $8 \times 2 = 16$, we can change $\frac{5}{8}$ into sixteenths.
* Multiply the top and bottom of $\frac{5}{8}$ by 2: $\frac{5 \times 2}{8 \times 2} = \frac{10}{16}$.
* Now subtract: $\frac{10}{16} - \frac{7}{16} = \frac{3}{16}$.

2) $\frac{1}{2} - \frac{1}{4}$
* The denominators are 2 and 4. Since $2 \times 2 = 4$, we change $\frac{1}{2}$ into fourths.
* Multiply the top and bottom of $\frac{1}{2}$ by 2: $\frac{1 \times 2}{2 \times 2} = \frac{2}{4}$.
* Now subtract: $\frac{2}{4} - \frac{1}{4} = \frac{1}{4}$.

3) $\frac{1}{2} - \frac{3}{8}$
* The denominators are 2 and 8. Since $2 \times 4 = 8$, we change $\frac{1}{2}$ into eighths.
* Multiply the top and bottom of $\frac{1}{2}$ by 4: $\frac{1 \times 4}{2 \times 4} = \frac{4}{8}$.
* Now subtract: $\frac{4}{8} - \frac{3}{8} = \frac{1}{8}$.

4) $\frac{11}{16} - \frac{1}{2}$
* The denominators are 16 and 2. We change $\frac{1}{2}$ into sixteenths.
* Multiply the top and bottom of $\frac{1}{2}$ by 8: $\frac{1 \times 8}{2 \times 8} = \frac{8}{16}$.
* Now subtract: $\frac{11}{16} - \frac{8}{16} = \frac{3}{16}$.

5) $\frac{3}{4} - \frac{9}{16}$
* The denominators are 4 and 16. We change $\frac{3}{4}$ into sixteenths.
* Multiply the top and bottom of $\frac{3}{4}$ by 4: $\frac{3 \times 4}{4 \times 4} = \frac{12}{16}$.
* Now subtract: $\frac{12}{16} - \frac{9}{16} = \frac{3}{16}$.

6) $\frac{3}{4} - \frac{3}{8}$
* The denominators are 4 and 8. We change $\frac{3}{4}$ into eighths.
* Multiply the top and bottom of $\frac{3}{4}$ by 2: $\frac{3 \times 2}{4 \times 2} = \frac{6}{8}$.
* Now subtract: $\frac{6}{8} - \frac{3}{8} = \frac{3}{8}$.

7) $\frac{1}{4} - \frac{1}{8}$
* The denominators are 4 and 8. We change $\frac{1}{4}$ into eighths.
* Multiply the top and bottom of $\frac{1}{4}$ by 2: $\frac{1 \times 2}{4 \times 2} = \frac{2}{8}$.
* Now subtract: $\frac{2}{8} - \frac{1}{8} = \frac{1}{8}$.

8) $\frac{7}{8} - \frac{7}{16}$
* The denominators are 8 and 16. We change $\frac{7}{8}$ into sixteenths.
* Multiply the top and bottom of $\frac{7}{8}$ by 2: $\frac{7 \times 2}{8 \times 2} = \frac{14}{16}$.
* Now subtract: $\frac{14}{16} - \frac{7}{16} = \frac{7}{16}$.

9) $\frac{5}{8} - \frac{1}{2}$
* The denominators are 8 and 2. We change $\frac{1}{2}$ into eighths.
* Multiply the top and bottom of $\frac{1}{2}$ by 4: $\frac{1 \times 4}{2 \times 4} = \frac{4}{8}$.
* Now subtract: $\frac{5}{8} - \frac{4}{8} = \frac{1}{8}$.

10) $\frac{15}{16} - \frac{3}{4}$
* The denominators are 16 and 4. We change $\frac{3}{4}$ into sixteenths.
* Multiply the top and bottom of $\frac{3}{4}$ by 4: $\frac{3 \times 4}{4 \times 4} = \frac{12}{16}$.
* Now subtract: $\frac{15}{16} - \frac{12}{16} = \frac{3}{16}$.
