SAT Math Practice Exam

Answer B [(-3.0)(0.1)-(1.5)(0.2)]/5= [(-0.3)-(0.3)]/5=[(-0.6]/5= -0.12

Key takeaway: When you multiply a decimal number by another decimal number, the decimal shifts to the left. Count and total the number of digits to the right of the decimal points in all of the numbers you are multiplying and place the decimal in that position counting the digits from the right of the product.
