Question

If B={x|x is an integer, -3/2<x<9/2}, the elements of B are________. *​

Answer 1

Integer= a number which is not a fraction or decimal

but, -3/2 and 9/2 are fractions,

-3/2 = -1.5 and 9/2 = 4.5 (as decimal)

so, the closest integers for -1.5 are -1 and -2 (-2 < -1.5 < -1), likewise the closest integers for 4.5 are 4 & 5 (4 < 4.5 < 5)

now, as per given question,

B = {x:x is an integer, -3/2 < x < 9/2}

so, B = {-1, 0, 1, 2, 3, 4} ...ans
