Question

write 2 irrational no between 1/3 and 2/4

Answer 1

1/3 and 2/4 (1/2)
so 1/2= 0.5
1/3= 0.333.....
you have to find irrational numbers between them so pick number which are between 0.5 and 0.33 and make the number non-recurring like-
0.45763127849....
0.43678952134....

Answer 2

$1 \div 3 = 4 \div 12 \\ 2 \div 4 = 6 \div 12 \\ hence \: there \: are \: only \: 1 \: inbetween\:.... 4 \div 12 \: \: \: 5 \div 12 \: \: \: 6 \div 12 \\ \\ or \: \: \\ {1 \div }{3} = 2 \div 6 \\ 2 \div 4 = 1 \div 2 = 3 \div 6 \\ they \: haven't be any no inbetween$
