Question

arrange 0.5 ,4%,3:5 and 2/45 in descending order ​For maths

Answer 1

Answer:

3:5 > 0.5 > 2/45 > 4%

Step-by-step explanation:

Firstly, we would convert all of the given expressions in lowest form of fraction.

0.5 can be written as 5/10 or 1/2.

4% can be written as 4/100 or 1/25.

3:5 can be written as 3/5.

2/45 is in fraction form. So no need to change it.

Now, taking L.C.M. of all denominators (i.e. 2, 25 , 5 , 45) = 450.

We would convert these fractions into equivalent fractions with a common denominator,

1/2 = 1*225/2*225 = 225/450

1/25 = 1*18/25*18 = 18/450

3/5 = 3*90/5*90 = 270/450

2/45 = 2*10/45*10 = 20/450

Now we can easily arrange them in descending order --->

270/450 > 225/450 > 20/450 > 18/450

Or,

3/5 > 1/2 > 2/45 > 1/25

Or,

3:5 > 0.5 > 2/45 > 4%    <------ Answer
