Multiply −2 1/2 by −1 3/5. Write the answer as a decimal.
To multiply -2 1/2 by -1 3/5, we need to convert both mixed numbers into improper fractions.
-2 1/2 = -5/2

Multiply 6.5 by 0.3. Write the answer as a decimal.
To multiply 4 by -5/8, you simply multiply the whole number 4 by the numerator -5 and keep the denominator 8 the same.
Step 1: Multiply the whole number by the numerator: 4 * (-5) = -20.
Step 2: Write the result as a fraction: -20/8.
Step 3: Simplify the fraction by finding the greatest common divisor (GCD) of the numerator and denominator, which is 4. Divide both the numerator and denominator by 4.
-20 ÷ 4 / 8 ÷ 4 = -5/2.
Step 4: Convert the improper fraction -5/2 to a mixed number.
Divide the numerator (-5) by the denominator (2): -5 ÷ 2 = -2 remainder 1.
Write the mixed number as follows: -2 and 1/2.
Therefore, 4 multiplied by -5/8 is equal to -2 1/2 in simplest form.
