Question

(А+3 4/7)-1 2/7=4 3/7; 2 19/23-(5/23+b)=1 6/23; ( c-2 3/11)+5 1/11=7; 3 4/9+(8-d)=6 5/9.

Answer 1

(А+3 4/7)-1 2/7=4 3/7
а+3 47=4 37+1 27
а+3 47=5 57
а=5 57-3 47
а=2 17

2 19/23-(5/23+b)=1 6/23
523+b=2 1923-1 623
523+b=1 1323
b=1 1323-523
b=1 823

( c-2 3/11)+5 1/11=7
с-2 311=7-5 111
с-2 311=6 1111-5 111
с-2 311=1 1011
с=1 1011+2 311
с=3 1311=4 211
 
3 4/9+(8-d)=6 5/9
8-d=6 59-3 49
8-d=3 19
d=8-3 19
d=7 99-3 19
d=4 89
