I will do the more complicated looking one, you try the others
(−2/5)x−9<9/10
The LCD is 10, so let's multiply each term by +10, no need to reverse the inequality sign
-4x - 90 < 9
add 90 to both sides
-4x < 99
divide both sides by -4, note the reversal of the inequality sign since we divided by a negative
x > -99/4 or x > -24.75 if you prefer decimals
