64:8×5=
40:8×9=
321-36:9=
114+56:8=
24:8+49=
90:9-10=

Answer 1

a) 
81 : 9 x 6 = 9 x 6 = 54
b)
63 : 9 x 7 = 7 x 7 = 49
c)
64 : 8 × 5 = 8 x 5 = 40
d)
40 : 8 × 9 = 5 x 9 = 45
e)
321 - 36 : 9 = 321 - 4 = 317
f)
114 + 56 : 8 = 114 + 7 = 121
g)
24 : 8 + 49 = 3 + 49 = 52
h)
90 : 9 - 10 = 10 - 10 = 0

Answer 2

$81 \div 9 \times 6 = 9 \times 6 = 54$
$63 \div 9 \times 7 = 7 \times 7 = 49$
$64 \div 8 \times 5 = 8 \times 5 = 40$
$40 \div 8 \times 9 = 5 \times 9 = 45$
$321 - 36 \div 9 = 321 - 4 = 317$
$114 + 56 \div 8 = 114 + 7 = 121$
$24 \div 8 + 49 = 3 + 49 = 52$
$90 \div 9 - 10 = 10 - 10 = 0$
