Answer 1

Step-by-step explanation:

a) 1 kg= 1000g

4kg= 4000g

4000g+14g= 4014g

Now convert 4014g into kg

4014/1000= 4.014 kg

Now add 6 to 4.014= 10.014 kg

Ans is 10.014 kg

b) 1 km= 1000m

23km= 23000m

23000m+ 72m= 23072m

Now convert 23072m to km

23072/1000= 23.072 km

Now add 10 to 23.072= 33.072 km

Ans is 33.072 km

c) 1L = 1000mL

14L= 14000mL

14000mL+ 492mL= 14492mL

Now convert 14492 mL into L

14492/1000= 14.492 L

Now add 13 to 14.492 L= 27.492 L

Ans is 27.492 L

d) 1km= 1000m

1m= 100cm

Therefore, 1km= 1000×100 = 100000cm

7km= 700000cm

and 7m = 700cm

700000cm+ 700cm+ 7cm= 700707 cm

Now convert 700707 cm to km

700707/100000= 7.00707 km

Now add 7 to 7.00707 km= 14.00707 km

Ans is 14.00707 km
