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) = $10\frac{2}{3}$

8 + 4 × 6 ÷ 9

8 + 24 ÷ 9

$8 + 2\frac{2}{3}$

$10\frac{2}{3}$

(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
