What decimal number is represented by the shaded portion of the model?

0.57

Step-by-step explanation:

Step 1: Count the total amount of squares

10 by 10 square, so 100 squares in total

Step 2: Count how many rows have been filled

5 rows of 10, so 50 out of 100, or 0.50

Step 3: Count the rest

7 out of 100, so 0.07

Step 4: Add

0.07 + 0.50 = 0.57

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
