Пошаговое объяснение:

1. 7-(2/3)=6¹/₃=19/3.

2. 1³/₄-(1/6)=(7/4)-(1/6)=(7*3-1*2)/12=(21-2)/12=19/12.

3. (19/3)/(19/12)=19*12/(3*19)=4.

4. 1¹/₅+2²/₃+¹/₆=(6/5)+(8/3)+(1/6)=(6*6+8*10+1*5)/30=

=(36+80+5)/30=121/30.

5. 4*(121/30)=2*121/15=242/15=16²/₁₅

Verified answer

Пошаговое объяснение:

(7- 2/3):(1 3/4 - 1/6)*(1 1/5+2 2/3 + 1/6 )=

=9 7/15

7- 2/3=6 3/3-2/3=6 1/3=19/3

1 3/4 - 1/6=7/4-1/6=(7*3-1*2)/12=19/12

1 1/5+2 2/3 + 1/6=6/5+8/3+1/6=

=(6*6+3*10+1*5)/30=71/30

19/3:19/12=(19*12)/19*3=4

4*71/30=142/15=9 7 /15
