Answer 2

Răspuns:

Explicație pas cu pas:

( 81 + 54 ) ÷ 9 = 135 ÷ 9 = 15

( 81 + 54 ) ÷ 9 = 81 ÷ 9 + 54 ÷ 9 = 9 + 6 = 15

( 4488 + 2264 ) ÷ 8 = 6752 ÷ 8 = 844

( 4488 + 2264 ) ÷ 8 = 4488 ÷ 8 + 2264 ÷ 8 = 561 + 283 = 844

( 72 - 27 ) ÷ 3 = 45 ÷ 3 = 15

( 72 - 27 ) ÷ 3 = 72 ÷ 3 - 27 ÷ 3 = 24 - 9 = 15

( 4024 - 1916 ) ÷ 4 = 2108 ÷ 4 = 527

( 4024 - 1916 ) ÷ 4 = 4024 ÷ 4 - 1916 ÷ 4 = 1006 - 479 = 527
