Question

37×24+37×76+63×79+21×63

Answer 1

= 37 × 24 + 37 × 76 + 63 × 79 + 21 × 63

= 37 x (24 + 76)       + 63 x (79 + 21)

= 37 x 100                + 63 x 100

= (37 + 63) x 100

= 100 x 100

= 10 000

Answer 2

   37 x 24 + 37 x 76 + 63 x 79 + 21 x 63

=37 x (24 + 76) + 63 x (79 + 21)

=37 x 100 + 63 x 100

=100 x ( 37 + 63 )

=100 x 100

=10000

Answer 3

= 10000

Answer 4

37×24 + 37×76 + 63×79 + 21×63       

= 37 x ( 24 + 76 ) + 63 x ( 79 + 21)

= 37 x 100 +  63 x 100 

= ( 37 + 63 ) x 100 = 100 x 100 = 10 000 

Answer 5

37×24 + 37×76 + 63×79 + 21×63       

= 37 x ( 24 + 76 ) + 63 x ( 79 + 21)

= 37 x 100 +  63 x 100 

= ( 37 + 63 ) x 100

= 100 x 100
