Dividing 27÷3-27 \div 3 and 100÷(4)-100 \div (-4)

Apply the sign rules for integer division to evaluate each quotient:

  • 27÷3=9-27 \div 3 = -9: The dividend is negative and the divisor is positive—different signs—so the quotient is negative. Dividing the absolute values gives 27÷3=927 \div 3 = 9, and attaching the negative sign yields 9-9.
  • 100÷(4)=25-100 \div (-4) = 25: The dividend and divisor are both negative—same signs—so the quotient is positive. Dividing the absolute values gives 100÷4=25100 \div 4 = 25.

In each case, first determine whether the two numbers share the same sign or have different signs; that alone fixes the sign of the answer. Then divide the absolute values to find the numerical result. Each answer can be verified by multiplying: (9)(3)=27(-9)(3) = -27 and (25)(4)=100(25)(-4) = -100.
