Question

3. Using a suitable property, find the products of the
following:
(i) 132 x 95
(ii) 87 X 197
(iii) 305 x 104
(iv) 467 x 1002​

Answer 1

Answer

I) 132*95

=(100-5)*132 ( Distributive Property)

=(132*5)-(132*100)

=660*13200

=8712000

ii)87*197

=(90-3)*197(Distributive Property)

=(197*90)-(197*3)

=17730-591

=11817

iii)305*104

=305*(100+4) { Distributive Property}

=(305*100)+(305*4)

=30500+1220

=42700

iv)467*1002

=467(1000+2) { Distributive Property}

=(467*1000)+(467*2)

=467000+932

=467932
