Here are the solutions for the exercise. 1. Put proper signs '>', '<', '=' in the blanks: a) 2 × 5 = 10 Two tens = 20 Comparing 10 and 20: 10 < 20 b) 2 + 10 = 12 Eighteen = 18 Comparing 12 and 18: 12 < 18 c) 9 + 5 = 14 Comparing 14 and 14: 14 = 14 d) 10 + 2 = 12 Comparing 12 and 12: 12 = 12 e) 8 ones = 8 Comparing 8 and 17: 8 < 17 f) 1 ten 9 ones = 10 + 9 = 19 17 + 1 = 18 Comparing 19 and 18: 19 > 18 2. Break up into tens and ones: a) 17 = 1 ten 7 ones b) Forty = 40 = 4 tens 0 ones c) 24 = 2 tens 4 ones d) 6 + 8 = 14 = 1 ten 4 ones e) 4 + 4 = 8 = 0 tens 8 ones f) Thirty two = 32 = 3 tens 2 ones g) 16 + 2 = 18 = 1 ten 8 ones
