a) \(3\times 5=15\), \(7+15=22\). (1 pt)

b) \(7+3=10\), \(10\times 5=50\). (1 pt)

c) \(6\times 4=24\), \(40-24=16\). (1 pt)

d) \(40-6=34\), \(34\times 4=136\). (1 pt)

a) \(m=71-26=45\). (1 pt)

b) \(k=72\div 9=8\). (1 pt)

c) \(4\times n=39-7=32\), so \(n=32\div 4=8\). (1 pt)

a) \(m=50-3\times 9\). (1 pt)

b) \(3\times 9=27\) dollars. (1 pt)

c) \(m=50-27=23\). (1 pt)

d) Priya has 23 dollars left. (1 pt)

a) \(60+40=100\). (1 pt)

b) No: 79 is far from 100, so it is not reasonable. (1 pt)

c) \(58+41=99\). (1 pt)

a) 28 and 32. (1 pt)

b) All even, because each number is a multiple of 2 (4 is even and an even number times any whole number is even). (1 pt)

c) \(7\times 6=42\), because the order of the factors does not change the product. (1 pt)

a) 38 and 94 are even; 71 and 115 are odd. (1 pt)

b) \(25+19=44\) even (odd + odd). \(8\times 7=56\) even (one factor is even). \(9+6=15\) odd (odd + even). (1 pt)

c) \(29=2\times 14+1\): 14 pairs and 1 child left over. (1 pt)
