Question

find 20 rational number between 2 upon 3 and 4 upon 5​

Answer 1

Step-by-step explanation:

20 irrational no between 2/3 and 4/5 are

first we will take LCM of denominators i.e 3 and 5

the LCM of 3 and 5 is 15

now both the fractions are multiplied to such a number so that the denominators of both fraction will be equal to 15

2/3 ×5/5 = 10/15 and 4/5 × 3/3= 12/15

now wel will use the rule (x+1) i.e will will add 1 to both the denominators 15

15+1 =16

now we will multiply both the fractions by 16

10/15 ×16/16 =160/240

12/15 × 16/16 =192/240

now you can find 20 numbers between 2/3 and 4/5

numbers are {161/240 ,162/240,163/240,

164/240 , 165/240 ,166/240 ,167/240 , 168/240 , 169/240 , 170/240 , 171/240,

172/240 ,173/240 ,174/240 ,175/240 ,176/240, 177/240, 178/240 ,179/240 ,180/240}
