а) p=6,q=5
б) p=7,2, q=12,5
в) p=3 21/25:32,q=9,5:7 3/5
г) p=14,4×7/10,q=2,1÷3/10

​

Answer 1

а) p=6,q=5

3p/2q-2p/3q=9p/6q-4p/6q=5p/6q

5×6/6×5=30/30=1

b) p=7,2,q=12,5

3p/2q-2p/3q=9p/6q-4p/6q=5p/6q

5×7,2/6×12,5

36/75=12/25

в) 3p/2q-2p/3q=9p/6q-4p/6q=5p/6q

p=3 21/25:32=96:32=3

p=3

q=9,5:7 3/5=9,5:38/5=5/4

5×3/6×5/4=15/15/2=2

г) 3p/2q-2p/3q=9p/6q-4p/6q=5p/6q

p=14,4×7/10=252/25

q=2,1:3/10=7

5×252/25/6×7=252/5/42=6/5
