Question

The length of a register is ⅔ m. Express the length in cm and mm.​

Answer 1

Answer:

Solution 6:

(a) 10 mm = 1 cm

1mm = \frac{1}{10}cm

2 mm = \frac{1}{10}\times2=\frac{2}{10} cm = 0.2 cm

(b) 10 mm = 1 cm

1 mm = \frac{1}{10} cm

30 mm = \frac{1}{10}\times30=3.0 cm

(c) 10 mm = 1 cm

1 mm = \frac{1}{10} cm

116 mm = \frac{1}{10}\times116=\frac{116}{10}=11.6 cm

(d) 10 mm = 1 cm

1 mm = \frac{1}{10} cm

4 cm + 2 mm = 4+\frac{2}{10} cm = 4 + 0.2 = 4.2 cm

(e) 10 mm = 1 cm

1 mm = \frac{1}{10} cm

162 mm = \frac{1}{10}\times162=\frac{162}{10}=\ 16.2 cm

(f) 10 mm = 1 cm

1 mm = \frac{1}{10} cm

83 mm = \frac{1}{10}\times83=\frac{83}{10}=\ 8.3 cm
