NEED HELP ALGEBRA 1

Answer 1

Answer: E) 1/5

========================================================

Method 1

Use your calculator to find the decimal version of each fraction

• 4/10 = 0.40
• 12/25 = 0.48
• 14/20 = 0.70
• 28/50 = 0.56
• 1/5 = 0.20

We see that 0.20 is the smallest decimal of the list, so 1/5 is the smallest fraction of the list.

----------------------------

Method 2

To compare fractions, we need to get all of the denominators to the same value. A good target is the lowest common denominator (LCD)

In this case, the LCD is 100

• 4/10 = 40/100 .... multiply top and bottom by 10
• 12/25 = 48/100 .... multiply top and bottom by 4
• 14/20 = 70/100 .... multiply top and bottom by 5
• 28/50 = 56/100  .... multiply top and bottom by 2
• 1/5 = 20/100  .... multiply top and bottom by 20

The last fraction has the smallest denominator, so 1/5 is the smallest.

Answer 2

The answer is E

1/5
