Change these fractions into decimal fractions.

Here are the solutions for the fractions and sums: Change these fractions into decimal fractions. a) Step 1: Divide the numerator by the denominator. (4)/(10) = 0.4 The decimal fraction is 0.4. b) Step 1: Divide the numerator by the denominator. (2)/(10) = 0.2 The decimal fraction is 0.2. c) Step 1: Divide the numerator by the denominator. (5)/(10) = 0.5 The decimal fraction is 0.5. d) Step 1: Divide the numerator by the denominator. (37)/(100) = 0.37 The decimal fraction is 0.37. e) Step 1: Divide the numerator by the denominator. (19)/(100) = 0.19 The decimal fraction is 0.19. f) Step 1: Divide the numerator by the denominator. (25)/(100) = 0.25 The decimal fraction is 0.25. Write a plus and minus sum for each of the following, using the green and red shaded squares. a) The image already provides the sums for this part. Addition: (2)/(10) + (8)/(10) = (10)/(10) Subtraction: (10)/(10) - (8)/(10) = (2)/(10) b) Step 1: Count the green and red squares. There are 4 green squares and 3 red squares out of 10 total. Step 2: Write the addition and subtraction sums. Addition: (4)/(10) + (3)/(10) = (7)/(10) Subtraction: (7)/(10) - (3)/(10) = (4)/(10) c) Step 1: Count the green and red squares. There are 5 green squares and 2 red squares out of 10 total. Step 2: Write the addition and subtraction sums. Addition: (5)/(10) + (2)/(10) = (7)/(10) Subtraction: (7)/(10) - (2)/(10) = (5)/(10) d) Step 1: Count the green and red squares. There are 30 green squares and 60 red squares out of 100 total. Step 2: Write the addition and subtraction sums. Addition: (30)/(100) + (60)/(100) = (90)/(100) Subtraction: (90)/(100) - (60)/(100) = (30)/(100) e) Step 1: Count the green and red squares. There are 50 green squares and 40 red squares out of 100 total. Step 2: Write the addition and subtraction sums. Addition: (50)/(100) + (40)/(100) = (90)/(100) Subtraction: (90)/(100) - (40)/(100) = (50)/(100) That's 2 down. 3 left today — send the next one.
