Inequalities Reminder < : less than ≤ : less than or equal to > : greater than ≥ : greater than or equal to To see some more examples like this, watch the Corbettmaths video: https: //corbettmathsprimary. com/2 018/07/20/inequality-signs-video/

Greater Than or Less Than Put the correct sign (<, > or =) between these numbers. Remember – the crocodile always eats the bigger number! 12 43 3+6 20 + 8 46 88 22 + 3 < < < > = > > 35 47 10 25 30 + 16 70 + 17 20 + 2
