Answer 2

Answer:

Step-by-step explanation:

(i) 1g 36mg (mg)

we know that 1 gram = 1000milligram

since we have to convert the unit into mg we multiply 1000 x 1g + 36mg.

=1036mg.

(ii)3kg 400g (g)

1 kg = 1000 g

∵ we should convert the whole thing into g.

3 x 1000 + 400 = 3400g

(iii) 5kg 500g (kg)

1kg = 1000g

converting g to kg

when convert a smaller unit to a higher unit we divide the required value

5kg + 500 ÷ 1000

= 5 + 0.5kg

= 5.5kg

(iv)1kg 250g (kg)

converting g to kg

1kg + 250 ÷ 1000

=1 + 0.25 kg

=1.25 kg
