3300 g + 1100 mg = ?? kg.
Conversion:
1 kg = 1,000 g.
1 kg = 10,00,000 mg.
3,300 g + 1,100 mg = (3,300 ÷ 1,000) + (1,100 ÷ 10,00,000)
= 3.3 + 0.0011
= 3.3011 kg.
Question 13.
2200 g – 340 mg = ____________ g
Answer:
2200 g – 340 mg = 2199.66 g.
Explanation:
2200 g – 340 mg = ?? g.
Conversion:
1 g = 1,000 mg.
2200 g – 340 mg = 2200 – (340 ÷ 1,000)
= 2200 – 0.34
= 2199.66 g.
Question 14.
2.3 kg + .66kg = ____________ g
Answer:
2.3 kg + .66kg = 2,960 g.
Explanation:
2.3 kg + .66kg = ?? g.
Conversion:
1 kg = 1,000 g.
2.3 kg + .66kg = (2.3 × 1,000) + (0.66 × 1,000)
= 2300 + 660
= 2,960 g.
Question 15.
1 mg + 1 g + 1 kg = ____________ kg
Answer:
1 mg + 1 g + 1 kg = 1.001001 kg.
Explanation:
1 mg + 1 g + 1 kg = ?? kg.
Conversion:
1 kg = 1,000 g.
1 kg = 10,00,000 mg.
1 mg + 1 g + 1 kg = (1 ÷ 10,00,000) + (1 ÷ 1,000) + 1
= 0.000001 + 0.001 + 1
= 1.001001 kg.
Question 16.
15 g – 15 cg – 15 mg = __________ g
Answer:
15 g – 15 cg – 15 mg = 14.835 g.
Explanation:
15 g – 15 cg – 15 mg = ?? g.
Conversion:
1 g = 100 cg.
1 g = 1,000 mg.
15 g – 15 cg – 15 mg = 15 – (15 ÷ 100) – (15 ÷ 1,000)
= 15 – 0.15 – 0.015
=14.85 – 0.015
= 14.835 g.
Question 17.
42 g + 100 mg = ___________ cg
Answer:

Explanation:
42 g + 100 mg = ?? cg.
Conversion:
1 g = 100 cg.
1 mg = 0.1 cg.
42 g + 100 mg = (100 × 42) + (100 × 0.1)
= 4,200 + 10
= 4,210 cg.
Question 18.
35 g + 3500 g = ____________ kg
Answer:
35 g + 3500 g = 3.535 kg.
Explanation:
35 g + 3500 g = ?? kg.
Conversion:
1 kg = 1,000 g.
35 g + 3500 g = (35 ÷ 1,000) + (3,500 ÷ 1,000)
= 0.035 + 3.5
= 3.535 kg.
Question 19.
100 kg – 2100 g = ____________ kg
Answer:
100 kg – 2100 g = 97.9 kg.
Explanation:
100 kg – 2100 g = ?? kg.
Conversion:
1 kg = 1,000 g.
100 kg – 2,100 g = 100 – (2,100 ÷ 1,000)
= 100 – 2.1
= 97.9 kg.
Question 20.
33 g + 33 cg + 33 mg = ____________ g
Answer:
33 g + 33 cg + 33 mg = 33.363 g.
Explanation:
33 g + 33 cg + 33 mg = ?? g.
Conversion:
1 g = 1,000 mg.
1 g = 100 cg.
33 g + 33 cg + 33 mg = 33 + (33 ÷ 100) + (33 ÷ 1,000)
= 33 + 0.33 + 0.033
= 33.33 + 0.033
= 33.363 g.
