## Problems

1. Archer made a tunnel for his hamster out of two cardboard tubes. One tube was $8 \dfrac{5}{8} \, \text{in}$ long. The other tube was $7 \dfrac{6}{8} \, \text{in}$ long.

What is the total length of the tunnel?

______ inches

2. Kayden walks $\dfrac{4}{5} \, \text{kilometers}$ to a friend's house. Then he and his friend walk $1 \dfrac{3}{5} \, \text{kilometers}$ more to go fishing at their favorite pond.

How far did Kayden walk all together?

______ kilometers

3. After a rain storm, Lily measures the depth of several puddles in her backyard. She records her results in a table.

 Puddle Depth(inches) On the lawn $\dfrac{3}{4}$ On the sidewalk $\dfrac{2}{4}$ Under the swing $1 \dfrac{1}{4}$

How much deeper was the puddle under the swing than the puddle on the sidewalk?

______ inches

4. Kyra and some friends go to a climbing gym. She records how high each person climbed.

 Person Height (m) Kyra $5 \dfrac{40}{100}$ Jake $7 \dfrac{10}{100}$ Mynna $4 \dfrac{85}{100}$

What is the total height climbed by Kyra and Jake?

_____ meters

1. The total length of the tunnel is $16 \dfrac{3}{8}$ inches.
2. Kayden walked $2 \dfrac{2}{5}$ kilometers all together.
3. The puddle under the swing was $\dfrac{3}{4}$ inch deeper than the puddle on the sidewalk.
4. Kyra and Jake climbed a total of $12 \dfrac{50}{100}$ meters.
We could also write this as $12 \dfrac{1}{2}$ meters.
