Question

вычислите (4/3 + 1/9) ÷ 3 ; (1/2 - 1/3)×3 очень тороплюсь, подскажите пожалуйста

Answer 1

(4/3 + 1/9) : 3 = ((12+1)/9) : 3 = 13/9 : 3/1 = 13/9 * 1/3 = 13/27
(1/2 - 1/3) * 3 = ((3-2)/6) * 3 = 1/6 * 3/1 = 1/2

Answer 2

(4/3 + 1/9) ÷ 3 = (4х3/9 + 1/9) ÷ 3 = (12/9 + 1/9) ÷ 3 = 13/9 ÷ 3 =
= 13х1/9х3 = 13/27
