Question 5 Fill in the following blanks appropriately:We do it one by one 5.5 km Given that 1 km = 1000 m Thus, 5.5 km = 5.5 × 1000 m = 55/10 × 1000 = 55 × 100 = 5,500 m 35 cm Given that 1 m = 100 cm 100 cm = 1 m 1 cm = 𝟏/𝟏𝟎𝟎 m Thus, 35 cm = 35 × 1/100 m = 35/100 = 035/100 = 0.35 m 14.5 cm Given that 1 cm = 10 mm Thus, 14.5 cm = 14.5 × 10 mm = 145/10 × 10 = 145 mm 68 g Given that 1 kg = 1000 g 1000 g = 1 kg 1 g = 𝟏/𝟏𝟎𝟎𝟎 kg Thus, 68 g = 68 × 1/1000 kg = 68/1000 = 0068/1000 = 0.068 kg 9.02 m Given that 1 m = 100 cm 1 m = 100 × 1 cm 1 m = 100 × 10 mm 1 m = 1000 mm Thus, 9.02 m = 9.02 × 1000 mm = 902/100 × 1000 = 902 × 10 = 9020 mm 124.5 ml Given that 1 l = 1000 ml 1000 ml = 1 l 1 ml = 𝟏/𝟏𝟎𝟎𝟎 l Thus, 125.5 ml = 125.5 × 1/1000 l = 1255/10 × 1/1000 = 1255/10000 = 01255/10000 = 0.1255 l
