Question

jessica is measering two line segments. the first line segment is 30 cm long. the second line segment is 500 mm long. how long are the two line segments together?

Answer 1

Answer:

80cm

Explanation:

when we convert 500mm to cm it becomes 50 cm

Answer 2

One line segment measures 30 cm = 300mm

Another line segment measures 500 mm

Note : You can add two quantities only when they

possess same units . You can either change both of them to 'cm' or 'mm'.

The two segments in together would measure

= 800 mm or 80 cm
