1 cm + 7 mm
= 1 cm +

cm
= 1 cm + 0.7 cm
= 1.7 cm
The first one is 1.7 cmThe second one shows 11 inches and 5/16 inches. Between number 11 and 12, there are 16 strips and the pointer lies on fifth strip, thus it show 5/16 inches.
The second one is 11
inches.The third one shows 13 cm and 8 mm. We need to convert mm into cm.
13 cm + 8 mm
= 13 cm + 0.8 cm
= 13.8 cm
The third one is 13.8 mm
(40 seconds) / (2000 rotations) =
