• -180
• 0
• -2/7

Answer 3

Let's solve each of these equations step by step:

1. 4 × (-45): 4 × (-45) = -180

2. 0 ÷ (-89 5/8): When dividing by a negative number or a negative fraction, the result will be negative. So, 0 ÷ (-89 5/8) = 0

3. (3/8) ÷ (-1 5/16): To divide fractions, you can invert the divisor (the second fraction) and multiply. First, convert the mixed number to an improper fraction:

   -1 5/16 = -21/16 (when the whole number is negative, make the fraction negative)

   Now, divide: (3/8) ÷ (-21/16) = (3/8) × (-16/21)

   You can simplify this fraction by canceling common factors between the numerators and denominators: (3/8) × (-16/21) = (3 × -16) / (8 × 21) = -48 / 168

   To further simplify, you can divide both the numerator and denominator by their greatest common divisor, which is 24: (-48 ÷ 24) / (168 ÷ 24) = -2/7

So, the results are:

1. 4 × (-45) = -180
2. 0 ÷ (-89 5/8) = 0
3. (3/8) ÷ (-1 5/16) = -2/7
