Question

Write the fractions in order from least to greatest use benchmarks and a number line:1/5,2/3,5/8

Answer 1

You can convert the fractions into decimals or give them the same denominator:

Method 1)
1/5 = 0.2
2/3 = 0.666
5/8 = 0.625
Answer: 1/5, 5/8, 2/3

Method 2)
1/5 = 24/120
2/3 = 80/120
5/8 = 75/120
Answer: 24/120(1/5), 75/120(5/8), 80/120(2/3).

Answer 2

The easiest way would be to convert the fractions into decimals.

1/5 = .2

2/3 = .666666

5/8 = .625

So from least to greatest would be 1/5, 5/8 , 2/3

Another way would be to find the common denominator

1/5 = 24 /120

5/8 = 75 /120

2/3 = 80 /120

And as you can tell from your numerators 24, 75, 80 that would be the order from least to greatest.
