Answer 1

Răspuns:

a) 205 × (147+453)= 123 000

205 × 600 = 123 000

( 205 × 147 ) + ( 205 × 453 ) = 123 000

30 135 + 92 865 = 123 000

b ) ( 561 + 232 ) × 386 = 306 098

793 × 386 = 306 098

( 561 × 386 ) + ( 232 × 386 ) = 306 098

216 546 + 89 552 = 306 098

c) 600 × ( 700 - 389 ) = 186 600

600 × 311 = 186 600

( 600 × 700 ) - ( 600 × 389) = 186 600

420 000 - 233 400 = 186 600
