Here are the solutions for the subtraction problems:

:

\begin{align*} & \quad 48 \text{ m } 65 \text{ cm} \\ &- \quad 12 \text{ m } 15 \text{ cm} \\ \hline \end{align*}

Subtract the centimeters.
$65 \text{ cm} - 15 \text{ cm} = 50 \text{ cm}$
Subtract the meters.
$48 \text{ m} - 12 \text{ m} = 36 \text{ m}$
The result for the first problem is:
$\boxed{\text{36 m 50 cm}}$
:
$\begin{align*} & \quad 120 \text{ m } 28 \text{ cm} \\ &- \quad 85 \text{ m } 19 \text{ cm} \\ \hline \end{align*}$
Subtract the centimeters.
$28 \text{ cm} - 19 \text{ cm} = 9 \text{ cm}$
Subtract the meters.
$120 \text{ m} - 85 \text{ m} = 35 \text{ m}$
The result for the second problem is:
$\boxed{\text{35 m 9 cm}}$
:
$\begin{align*} & \quad 28 \text{ m } 28 \text{ cm} \\ &- \quad 18 \text{ m } 19 \text{ cm} \\ \hline \end{align*}$
Subtract the centimeters.
$28 \text{ cm} - 19 \text{ cm} = 9 \text{ cm}$
Subtract the meters.
$28 \text{ m} - 18 \text{ m} = 10 \text{ m}$
The result for the third problem is:
$\boxed{\text{10 m 9 cm}}$
