Question

What decimal from the following represent the shaded part in the figure given below?

Answer 1

There are hundred squares in one grid which form a one whole.
One grid is completely shaded so there is 1 whole.
The other grid has 42 squares shaded.
Fraction of shaded part = $\frac{42}{100}$
Converting into decimal part, $\frac{42}{100}=0.42$

Thus, the total shaded part is 1 + 0.42 = 1.42
