Use properties of operations and rules for multiplying signed numbers to multiply −2/5 by 3/10
. Write the answer in simplest form.
To multiply fractions, we simply multiply the numerators together and the denominators together.
Hence, (-2/5) * (3/10) = (-2 * 3) / (5 * 10) = -6 / 50.
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2 in this case.
Therefore, (-6/50) ÷ 2 = -3/25.
The final answer in simplest form is -3/25.
u sure?
Apologies for the mistake in my previous response. You are right, the simplification step was incorrect.
To multiply fractions, we multiply the numerators together and the denominators together:
(-2/5) * (3/10) = (-2 * 3) / (5 * 10) = -6/50.
Now, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 2:
-6/50 ÷ 2 = -3/25.
So, the correct answer, in simplest form, is -3/25.
Multiply 4 by −58. Write the answer as a mixed number in simplest form.
To multiply two numbers, we simply multiply their values:
4 * -58 = -232.
To write this answer as a mixed number, we will divide the product (-232) by the absolute value of the second number (-58):
-232 ÷ 58 = -4.
The quotient (-4) becomes the whole number in the mixed number. The remainder is 0, so there is no fraction component.
Therefore, the answer as a mixed number in simplest form is -4.
Multiply 4 by −5/8. Write the answer as a mixed number in simplest form.
To multiply a whole number by a fraction, we multiply the whole number by the numerator of the fraction and keep the same denominator.
4 * (-5/8) = (-20/8) = -2.5.
To write this answer as a mixed number, we will divide the numerator (-20) by the denominator (8):
-20 ÷ 8 = -2 remainder 4.
The quotient (-2) becomes the whole number in the mixed number, and the remainder (4) becomes the numerator of the fractional part. The denominator remains the same.
Therefore, the answer as a mixed number in simplest form is -2 4/8. We can simplify this fraction further by dividing both the numerator and denominator by their greatest common divisor, which is 4:
(-2 * 4) / (8 * 4) = -8/32.
Simplifying by dividing both the numerator and denominator by 8, we get:
-1/4.
So, the final answer as a mixed number in simplest form is -2 1/4.
Multiply −19.3 by 6.
To multiply a decimal number by a whole number, we simply multiply their values.
(-19.3) * 6 = -115.8.
Therefore, the product of -19.3 and 6 is -115.8.
