Question

Now express $17\frac{1}{2}$ kg in grams. [2 MARKS]

Answer 1

In kilograms: 1 Mark
In grams: 1 Mark

1 Kilogram = 1000 grams
Or 1 gram=$\frac{1}{1000}$ kilograms

Let x kilograms = 3460 g

$=\left(\frac{3460}{1000}\right)$ kilograms

= 3.460 kilograms

3460 grams = 3.460 kilograms

Now $17\frac{1}{2}\text{kg}=\frac{17\times 2+1}{2}$

=$\frac{34+1}{2}$

=$\frac{35}{2}\text{kg}$

=$\frac{35}{2}\times 1000\text{gms}$

=$(35\times 500)\text{gm}$

=$17500\text{gms}$
