To multiply fractions, you simply multiply the numerators together and the denominators together.
So, (-2/5) * (3/10) = (-2 * 3) / (5 * 10) = -6/50
However, the answer can be simplified further. Both -6 and 50 are divisible by 2, so we can divide both the numerator and denominator by 2.
-6/50 simplifies to -3/25.
Therefore, the answer in simplest form is -3/25.
Multiply 4 by −5/8. Write the answer as a mixed number in simplest form.
To multiply a whole number by a fraction, you can convert the whole number to a fraction with a denominator of 1, and then multiply the fractions.
4 can be written as 4/1.
So, (4/1) * (-5/8) = (4 * -5) / (1 * 8) = -20/8.
To simplify the fraction, you can divide both the numerator and denominator by their greatest common divisor, which is 4.
-20/8 simplifies to -5/2.
Now, let's write the answer as a mixed number.
-5/2 can be written as -2 1/2.
Therefore, the answer in simplest form as a mixed number is -2 1/2.
Multiply 6.5 by 0.3. Write the answer as a decimal.
To multiply decimal numbers, you can simply multiply them as if they were whole numbers and then adjust the decimal point in the final answer.
6.5 * 0.3 = 19.5
Therefore, the answer as a decimal is 19.5.
Multiply −19.3 by 6.
To multiply decimal numbers, you can ignore the decimal points, multiply the numbers as if they were whole numbers, and then adjust the decimal point in the final answer.
-19.3 * 6 = -115.8
Therefore, the answer as a decimal is -115.8.
