14.96 ÷ 2.2 = 6.8
Check: 2.2 × 6.8 = 14.96.
Likely mistake: Steve treated 2.2 as 22 (moving the decimal in the divisor only) and computed 14.96 ÷ 22 = 0.68. When removing the decimal from the divisor you must also move the decimal in the dividend (multiply both by 10), so the correct division is 149.6 ÷ 22 = 6.8.
