b. 199 x 9
c. 483 x 99
d. 2456 x 99
e. 5682 x 99
a. 86 x 9 = (86 x 10) – 86
= 860 – 86
= 774
b. 199 x 9 = (199 x 10) -199
= 1990 – 199
= 1791
c. 483 x 99 = (483 x 100) – 483
= 48300 – 483
= 47817
d. 2456 x 99 = (2456 x 100) – 2456
= 245600 – 2456
= 243144
e. 5682 x 99 = (5682 x 100) – 5682
= 568200 – 5682
= 562518
