Answer 1

15х24=15х(6х4)=(15х6)х4=90х4=360
18x35=18x(5x7)=(18x5)x7=90x7=630
55x18=55x(2x9)=(55x2)x9=110x9=990
15x14=15x(2x7)=(15x2)x7=30x7=210
12x45=12x(5x9)=(12x5)x9=30x9=270
35x22=35x(11x2)=(35x11)x2=385x2=770
150х12=150x(2x6)=(150x2)x6=300x6=1800
75x16=75x(2x8)=(75x2)x8=150x8=1200
250x24=250x(6x4)=(250x6)x4=1500x4=6000
125x12=125x(2x6)=(125x2)x6=250x6=1500
