Answers

60x0.8=48
60-48=12
12/0.4=30
30-12=18
18/0.3=60
60-18=42
42/0.75=56
The bottom diagram is 56 units

Answer:

56

Step-by-step explanation:

80% of sixty is 48 so the 20% is 12.

Example:

12 is 40 percent of the next problem.

12/.4 = 3030*.6 = 18

18 is now 30% of the next strip.

18/.3 = 6060*.7 = 42

42 now is 75% of the last strip

42/.75 = 56

56 is the Answer.

Step-by-step explanation:

Answer:

1 ) n = -1/4

2 ) x = 3/5

Step-by-step explanation:

First equation:

1/2 = n + 3/4

Step 1 - Flip the equation:

n + 3/4 = 1/2

Step 2 - Subtract 3/4 from both sides:

n + 3/4 - 3/4 = 1/2 - 3/4 =

n = -1/4

Answer: n = -1/4

Second equation:

x - 1/2 = 1/10

Step 1 - Simplify both sides of the equation:

x + -1/2 = 1/10

Step 2 - Add 1/2 to both sides:

x + -1/2 + 1/2 = 1/10 + 1/2

x = 3/5

Answer: x = 3/5
