Answer 1

a) 3 x 45 + 3 x 15 = 3 x (45 + 15) = 3 x 60 = 180
b) 20 x 48 + 20 x 2 = 20 x (48 + 2) = 20 x 50 = 1000
c) 28 x 521 - 28 x 21 = 28 x (521 - 21)=28 x 500 = 14000
d) 23 x 718 - 162 x 23 = 23 x (718 - 162) = 23 x 556 = 12788
e) 15 x 38 + 15 x 162 = 15 x (38 +162) = 15 x 200 = 3000
f) 702 x 65 + 35 x 702 = 702 x ( 65 + 35) = 702 x 100 = 70200
g) 2413 x 1001 - 2413 = 2413 x (1001 - 1) = 2413 x 1000 = 2413000
h) 2029 x 599 + 2029= 2029 x (599 + 1) = 2029 x 600 =1217400
i) 1289 x 337 + 1289 x 663= 1289 x (337 + 663) = 1289 x 1000 = 1289000
