Hint: Recall the relationship between different units in the length system, especially between centimeter (cm), millimeter (mm) and meter (m). Use 1m = 100cm and 1m = 1000mm accordingly.

Complete step-by-step answer:

We know the relationship between meter (m) and centimeter (cm) and also between meter (m) and millimeter (mm).

The relationship between meter (m) and centimeter (cm) is as follows:

1 m = 100 cm

We can also express centimeter (cm) in terms of meter (m) using the above equation as follows:

1 cm = \[\dfrac{1}{{100}}\] m

When we divide any number by 100, we just need to move the decimal point by two places to the left, hence, when we divide 1 by 100, we shift the decimal point in 1.0 by two places to the left to get 0.01.

1 cm = 0.01 m

The relation between centimeter (cm) and millimeter (mm) is as follows:

1 cm = 10 mm

We can also express millimeter (mm) in terms of centimeter (cm) using the above equation as follows:

1 mm = \[\dfrac{1}{{10}}\] cm

When we divide any number by 10, we just need to move the decimal point by one place to the left, hence, when we divide 1 by 10, we shift the decimal point in 1.0 by one place to the left to get 0.1.

1 mm = 0.1 cm

Hence, the value of 15 mm in terms of cm is as follows:

15mm = 1.5 cm

Hence, the value of 23 cm 15 mm in terms of cm is as follows:

23 cm 15 mm = 23 + 1.5 cm

23 cm 15 mm = 24.5 cm

We now convert 24.5 cm to m as follows:

24.5 cm = 0.245 m

Hence, the answer is 0.245 m.

Note: You might make a mistake when you convert 23 cm 15 mm into cm as 23.15 which is wrong and you might end up with the answer as 0.2315.
