# Express as kg using decimals.

**(a)** 2 g

**(b)** 100 g

**(c)** 3750 g

**(d)** 5 kg 8 g

**(e)** 26 kg 50 g

To do:

We have to express the given numbers as kg using decimals.

Solution:

We know that,

$1\ kg=1000\ g$

This implies,

$1\ g=\frac{1}{1000}\ kg$

Therefore,

(a) $2\ g=2\times\frac{1}{1000}\ kg$

$=\frac{2\times1}{1000}\ kg$

$=\frac{2}{1000}\ kg$

$=0.002\ kg$

(b) $100\ g=100\times\frac{1}{1000}\ kg$

$=\frac{100\times1}{1000}\ kg$

$=\frac{100}{1000}\ kg$

$=0.1\ kg$

(c) $3750\ g=3750\times\frac{1}{1000}\ kg$

$=\frac{3750\times1}{1000}\ kg$

$=\frac{3750}{1000}\ kg$

$=3.75\ kg$

(d) $8\ g=8\times\frac{1}{1000}\ kg$

$=\frac{8\times1}{1000}\ kg$

$=\frac{8}{1000}\ kg$

$=0.008\ kg$

This implies,$5\ kg\ 8\ g=(5+0.008)\ kg$

$=5.008\ kg$

(e) $50\ g=50\times\frac{1}{1000}\ kg$$=\frac{50\times1}{1000}\ kg$

$=\frac{50}{1000}\ kg$

$=0.050\ kg$

This implies,$26\ kg\ 50\ g=(26+0.050)\ kg$

$=26.05\ kg$
