use 100 square grids
to shade 1.5 and what fraction would remain un shaded
100 - 1.5 = 98.5
To shade 1.5 out of 100 square grids, follow these steps:
1. Start by shading one complete square grid.
2. To shade half of a square, you can divide it diagonally from one corner to the opposite corner, and shade one of the resulting triangles.
3. Now, you have shaded 1.5 square grids out of 100.
To find the fraction that remains unshaded, follow these steps:
1. Convert the shaded squares to a fraction. We have shaded 1.5 out of 100 squares.
- Since each square can be considered as 1/100, we multiply this fraction by 1.5 to get (1/100) x 1.5 = 1.5/100.
2. Subtract the shaded fraction from 1 (whole). Since we need to find the remaining unshaded fraction, we subtract 1.5/100 from 1.
- 1 - 1.5/100 = 100/100 - 1.5/100 = 98.5/100.
3. Simplify the fraction, if possible. In this case, we can divide both the numerator and denominator by 0.5 to simplify.
- 98.5/100 ÷ 0.5/0.5 = 197/200.
Therefore, the fraction that remains unshaded is 197/200.
