Answer:
(8 + 4 × 6) ÷ 2 + 7
Step-by-step explanation:
8 + (4 × 6) ÷ 2 + 7 = 27
8 + 24 ÷ 2 + 7
8 + 12 + 7
27
8 + 4 × 6 ÷ (2 + 7) = 
8 + 4 × 6 ÷ 9
8 + 24 ÷ 9


(8 + 4 × 6) ÷ 2 + 7 = 23
(8 + 24) ÷ 2 + 7
32 ÷ 2 + 7
16 + 7
23
(8 × 4) + 6 ÷ 2 − 7 = 28
32 + 6 ÷ 2 - 7
32 + 3 - 7
35 - 7
28
A:B = 2:3
A=126
B=?
126/2=63
63x3=189
A=126
B=189
A:B = 126:189
