Question

During Cleanliness Week, children cleaned the public park in their town. They collected three-quarter kilograms of plastic bags and five and a half kilograms of other garbage. How much garbage did they collect in all?

Answer 1

1 kg = 1000 gm

So, `1/4` kg = `1000/4` = 250 gm

4)`overline1000`
  - 8            
   20
- 20            
   00            

Three quarters = `1/4 + 1/4 + 1/4`

= 250 + 250 + 250

= 750 gm

     250 

kg	gm
+ 5	7 5 0   5 0 0	Plastic Garbage
5 5 + 1	1 2 5 0    2 5 0

∴ 6 kg 250 gm.
