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
