Use properties of operations and rules for multiplying signed numbers to multiply −25 by 3/10
. Write the answer in simplest form.
To multiply -25 by 3/10, we can use the property of operations that states that the product of a negative number and a positive number is negative.
So, -25 multiplied by 3/10 is equal to (-25) * (3/10).
To simplify the multiplication, we can cancel common factors between the numerator and denominator. In this case, we can cancel a common factor of 5.
(-25) * (3/10) = (-5*5) * (3/2*5)
= -5 * 3/2
= -15/2
Therefore, -25 multiplied by 3/10 is equal to -15/2 in simplest form.
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 -2/5 by 3/10, we can use the property of operations that states that the product of two negative numbers or two positive numbers is positive.
So, -2/5 multiplied by 3/10 is equal to (-2/5) * (3/10).
To simplify the multiplication, we can multiply the numerators and denominators together.
(-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.
-6/50 = -3/25
Therefore, -2/5 multiplied by 3/10 is equal to -3/25 in simplest form.
Multiply 4 by −5/8. Write the answer as a mixed number in simplest form.(1 point)
To multiply 4 by -5/8, we can multiply the whole number 4 by the numerator -5, and keep the denominator 8 the same.
4 * (-5/8) = (-20/8)
Now, we simplify this fraction. The greatest common divisor of -20 and 8 is 4.
(-20/8) = -5/2
To write this mixed number in simplest form, we divide the numerator (-5) by the denominator (2).
-5/2 = -2 remainder 1
So, the answer is -2 and 1/2.
Multiply 6.5 by 0.3. Write the answer as a decimal.
To multiply 6.5 by 0.3, we can simply multiply the two numbers together:
6.5 * 0.3 = 1.95
So, the answer is 1.95.
Multiply −19.3 by 6.
To multiply -19.3 by 6, we can simply multiply the two numbers together.
-19.3 * 6 = -115.8
So, the answer is -115.8.
