Compare the following fraction <br>4/3 and 5/2<br>-3/2. -4/5​
zavuch27 [327]

Answer:

Step-by-step explanation:

to compare them, we need to convert them into like fractions

4/3 and 5/2

lcm of 3 and 2 is 6

4/3 × 2/2 = 8/6

5/2 × 3/3 = 15/6

15/6 is greater than 8/6

<em><u>so 5/2 is greater than 4/3</u></em>

similarly,

-3/2 and -4/5

we need to convert them into like fractions

lcm of 2 and 5 is 10

-3/2 × 5/5 = -15/10

-4/5 × 2/2 = -8/10

-8/10 is greater than -15/10

<u><em>so -4/5 is greater than -3/2</em></u>

Hope this helps
