what decimal number is illustrated?
Answer
Explanation:
Step1: Determine the value of each whole - grid
Each whole grid represents 1. There are 2 full - shaded grids, so their value is 2.
Step2: Determine the value of the partially - shaded grid
The third grid has 100 small squares in total and 78 are shaded. So the value of the shaded part of the third grid is 0.78.
Step3: Calculate the total decimal value
Add the values of the full grids and the partially - shaded grid. $2 + 0.78=2.78$.
Answer:
2.78
