Question: An ant goes 3 cm forward then goes 2 cm backwards and then finally 5 cm forward. What is the final position of the ant if the initial position of the ant is shown on the scale?

Options:
 A. 6 cm B. 7 cm C. 8 cm D. 9 cm
: C

Initial position of the ant = 2 cm Ant goes 3 cm forward = 2 cm + 3 cm =5 cm Ant goes 2 cm backward = 5 cm - 2 cm = 3 cm Finally, the ant goes 5 cm forward = 3 cm + 5 cm = 8 cm

The final position of the ant is 8 cm

Question 2. 1 kilometre = ______ metres
1.    10
2.    100
3.    1000
4.    10000
: C

The conversion factor for kilometre to metre is 1000.
When we convert a bigger unit (km) to a smaller unit (m), we multiply. Therefore, 1 km = 1×1000 = 1000 m
Question 3. Add 20 kilometres and 300 metres.
1.    320 km
2.    20.3 km
3.    23 km
4.    2.03 km
: B

We need to convert 300 m to km. To convert a smaller unit (m)to a bigger unit (km), we need to divide by the conversion factor. We know that 1000 m = 1 km 300 m = 3001000= 0.300 km. Hence, 20 km + 0.300 km = 20.300 km = 20.3 km
Question 4. Find the missing quantity:

1 L = 350 mL + ______ mL
1.    600
2.    650
3.    700
4.    750
: B

We know that 1 Litre = 1000 mL 1000 mL = 350 mL + _____ mL 1000 mL - 350 mL = _____ mL
= 650 mL

1000 mL = 350 mL + 650 mL
Question 5. Subtract: 1 mg from 20 mg
1.    19 m
2.    19 g
3.    19 mg
4.    1.9 g
: C

Since the units are same, the values can be easily subtracted 20 mg - 1 mg = 19 mg
