Comparing Fractions Answers


Introduction for Comparing Fractions Answers:

A fraction (from the Latin fractus, broken) is a number that can represent part of a whole. The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on. A much later development were the common or "vulgar" fractions which are still used today (½, ?, ¾, etc.) and which consist of a numerator and a denominator.

Comparing Fractions Answers - which are Smaller:

The examples show the fractions compare the smaller.

Comparing  fractions which are smaller: `1/7` or `2/9` ?

Solution:

The LCD for the denominators 7, 9 is 63.

Multiply the numerator `(1*9)/63` and `(2*7)/63` .

The solution for the fractions is `9/63` and `14/63`

When comparing the answers `1/7` is smaller.



Comparing the fractions which are smaller: `4/3` or `12/7` ?

Solution:

The LCD for the denominators 3, 7 is 21.

Multiply the numerator `(4*7)/21` and `(3*12)/21` .

The solution for the fractions is `28/21` and `36/21`

When comparing the answers `4/3 ` is smaller.

Comparing the fractions which are smaller: `17/9` or `21/8` ?

Solution:

Convert the given fractions in to decimal form.

Divide the fractions as (17÷9) and (21÷8).

The solution for the fractions is `17/9` = 1.88 and `21/8` = 2.62

When comparing the answers `17/9` is smaller.

Comparing Fractions Answers - which are Greater:

The examples show the fractions compare the greater.

Comparing the fractions which are greater: `13/7` or `5/3` ?

Solution:

The LCD for the denominators 7, 3 is 21.

Multiply the numerator `(13*3)/21` and `(7*5)/21` .

The solution for the fractions is `39/21` and `35/21`

When comparing the answers `13/7` is greater.

Comparing the fractions which are greater: `9/3` or `12/5` ?

Solution:

The LCD for the denominators 3, 5 is 15.

Multiply the numerator `(9*5)/15 ` and `(3*12)/15` .

The solution for the fractions is `45/15` and `36/15`

When comparing the answers `9/3` is greater.

Comparing the fractions which are greater: `23/8` or `33/6` ?

Solution:

Convert the given fractions in to decimal form.

Divide the fractions as (23÷8) and (33÷6).

The solution for the fractions is `23/8` = 2.875 and `33/6` = 5.5

When comparing the answers `33/6 ` is greater.
