Answer 2

Comparing Fractions

Let's compare the following fractions:

1. 5/8 and 3/4 2. 7/10 and 8/15 3. 4/11 and 3/8

To compare fractions, we can either find a common denominator and compare the numerators, or we can convert the fractions to decimals and compare the decimal values.

Comparing 5/8 and 3/4

To compare 5/8 and 3/4, we can find a common denominator. The least common multiple (LCM) of 8 and 4 is 8.

Converting both fractions to have a denominator of 8:

- 5/8 is equivalent to 5 * (8/8) = 40/64 - 3/4 is equivalent to 3 * (2/2) = 24/32

Now, we can compare the numerators:

- 40/64 is greater than 24/32 because 40 is greater than 24.

Therefore, 5/8 is greater than 3/4.

Comparing 7/10 and 8/15

To compare 7/10 and 8/15, we can find a common denominator. The LCM of 10 and 15 is 30.

Converting both fractions to have a denominator of 30:

- 7/10 is equivalent to 7 * (3/3) = 21/30 - 8/15 is equivalent to 8 * (2/2) = 16/30

Now, we can compare the numerators:

- 21/30 is greater than 16/30 because 21 is greater than 16.

Therefore, 7/10 is greater than 8/15.

Comparing 4/11 and 3/8

To compare 4/11 and 3/8, we can find a common denominator. The LCM of 11 and 8 is 88.

Converting both fractions to have a denominator of 88:

- 4/11 is equivalent to 4 * (8/8) = 32/88 - 3/8 is equivalent to 3 * (11/11) = 33/88

Now, we can compare the numerators:

- 32/88 is less than 33/88 because 32 is less than 33.

Therefore, 4/11 is less than 3/8.

To summarize the comparisons:

- 5/8 is greater than 3/4 - 7/10 is greater than 8/15 - 4/11 is less than 3/8
