Understanding Division with Decimals

The video tutorial explains how to divide -1.92 by 0.6. It begins by determining the sign of the quotient, which is negative because a negative number is divided by a positive number. The tutorial then sets up the division in long form and converts the divisor into a whole number by moving the decimal point. The same adjustment is made to the dividend. The video explains why this adjustment is valid by discussing equivalent fractions. The long division is performed, resulting in a quotient of 3.2, which is then adjusted to -3.2 due to the initial sign determination.

What is the sign of the quotient when a negative number is divided by a positive number?

• Positive

• Zero

• Undefined

• Negative

Why do we move the decimal point in both the divisor and the dividend?

• To make the dividend a whole number

• To make the divisor a whole number

• To change the sign of the quotient

• To simplify the division

What is the equivalent division problem after moving the decimal point in 1.92 divided by 0.6?

• 19.2 divided by 0.6

• 1.92 divided by 6

• 1.92 divided by 0.06

• 19.2 divided by 6

How many times does 6 go into 19 during the long division process?

• 3 times

• 5 times

• 2 times

• 4 times

What is the result of subtracting 18 from 19 in the long division process?

• 0

• 1

• 2

• 3

What is the final quotient of the division of negative 1.92 by 0.6?

• 0.32

• -0.32

• 3.2

• -3.2

Why is the final quotient negative?

• Because the divisor is negative

• Because the dividend is negative

• Because both numbers are negative

• Because a negative number is divided by a positive number
