(a)


Now, the weight of the car in Moon = $\frac{1}{6}$ of its weight on earth.

$\Rightarrow \frac{1}{6}$ of 420 kg

$\Rightarrow \frac{420}{6}$

$\Rightarrow 70kg$

$\therefore$ weight of the car in Moon = 70 kg only.


(b) There are 100 squares. 46 out of them are coloured. This picture shows forty-six hundredths.

To write 46 hundredths as a decimal, we use a place value chart.

The answer is 0.46.
