Question

Is 2.4 178 bar is a rational number if yes then explain?

Answer 1

let x = 2.4178 in 4178 bar -----------------(1)
multiply both sides by 10000
10000x = 10000*2.4178
10000x = 24178 -----------(2)
subtracting equation (1) from equation (2)
10000x = 24178 - 2.4178
10000x = 24176
x = 24176/10000
x= 12088/5000
x = 6044/2500
x = 3022/1250
x= 1511/625


1511/625 is a rational number because it is written in the form of p/q
