Your answer would be 0.87 as a decimal and 87/100 as a fraction.
To find these we need to find out how many little squares there are in total, and then how many shaded squares there are.
The shape is 10 squares by 10 squares, which means in total there are 10 × 10 = 100 squares in the whole shape.
To find the number of shaded squares we can count how many aren't shaded and subtract this from 100, and by doing this we get that there are 13 unshaded squares. 100 - 13 = 87 squares.
To convert this into a fraction, we can write it as , which we know is 87/100, which can't be simplified any further.
To convert this into a decimal, we can simply do the division 87 ÷ 100 (which is what the fraction represents), and this gives us 0.87
