Answer 1

Answer:

$13\dfrac{1}{4}\ inches$

Step-by-step explanation:

To find the total length, you should add all lengths and calculate the sum. There are

3 buttons of length $\frac{1}{4}$ inch

2 buttons of length $\frac{3}{8}$ inch

4 buttons of length $\frac{1}{2}$ inch

2 buttons of length $\frac{5}{8}$ inch

3 buttons of length $\frac{3}{4}$ inch

2 buttons of length $\frac{7}{8}$ inch

2 buttons of length 1 inch

2 buttons of length $1\frac{1}{4}$ inches

Total length:

$3\cdot \dfrac{1}{4}+2\cdot \dfrac{3}{8}+4\cdot \dfrac{1}{2}+2\cdot \dfrac{5}{8}+3\cdot \dfrac{3}{4}+2\cdot \dfrac{7}{8}+2\cdot 1+2\cdot 1\dfrac{1}{4}=\\ \\=\dfrac{3}{4}+\dfrac{3}{4}+2+\dfrac{5}{4}+\dfrac{9}{4}+\dfrac{7}{4}+2+2\cdot \dfrac{5}{4}=\\ \\=4+\dfrac{27}{4}+\dfrac{10}{4}=\\ \\=4+\dfrac{37}{4}=\\ \\=4+9\dfrac{1}{4}=\\ \\=13\dfrac{1}{4}$
