Explanation:

Step1: Multiply as whole numbers

$6 \times 6 = 36$
Count decimal places: 1 + 1 = 2. Place decimal: $0.36$

Step2: Multiply as whole numbers

$7 \times 8 = 56$
Count decimal places: 1 + 1 = 2. Place decimal: $0.56$

Step3: Multiply as whole numbers

$8 \times 9 = 72$
Count decimal places: 1 + 1 = 2. Place decimal: $0.72$

Step4: Multiply as whole numbers

$25 \times 2 = 50$
Count decimal places: 1 + 1 = 2. Place decimal: $0.50 = 0.5$

Step5: Multiply as whole numbers

$9 \times 27 = 243$
Count decimal places: 1 + 2 = 3. Place decimal: $0.243$

Step6: Multiply as whole numbers

$30 \times 3 = 90$
Count decimal places: 1 + 2 = 3. Place decimal: $0.090 = 0.09$

Step7: Multiply as whole numbers

$9 \times 41 = 369$
Count decimal places: 1 + 2 = 3. Place decimal: $0.369$

Step8: Multiply as whole numbers

$386 \times 43 = 16598$
Count decimal places: 2 + 1 = 3. Place decimal: $16.598$

Step9: Multiply as whole numbers

$841 \times 5 = 4205$
Count decimal places: 2 + 1 = 3. Place decimal: $4.205$

Step10: Multiply as whole numbers

$7 \times 232 = 1624$
Count decimal places: 1 + 2 = 3. Place decimal: $1.624$

Step11: Multiply as whole numbers

$175 \times 26 = 4550$
Count decimal places: 2 + 1 = 3. Place decimal: $4.550 = 4.55$

Step12: Multiply as whole numbers

$35 \times 246 = 8610$
Count decimal places: 1 + 2 = 3. Place decimal: $8.610 = 8.61$
