Use properties of operations and rules for multiplying signed numbers to multiply
A.-6/50
B. 3/5
C. -6/5
D. -3/25
To multiply signed numbers, we can follow the rules:
1. If the numbers have the same sign (both positive or both negative), the product is positive.
2. If the numbers have different signs (one positive and one negative), the product is negative.
Now let's multiply:
A. -6/50 * 3/5 = (-6 * 3) / (50 * 5) = -18/250 = -9/125
B. 3/5 * 3/5 = (3 * 3) / (5 * 5) = 9/25
C. -6/5 * -6/5 = (-6 * -6) / (5 * 5) = 36/25
D. -3/25 * -6/50 = (-3 * -6) / (25 * 50) = 18/125
Use properties of operations and rules for multiplying signed numbers to multiply -2/5 by 3/10
A.-6/50
B. 3/5
C. -6/5
D. -3/25
To multiply -2/5 by 3/10, we can simply multiply the numerators and denominators:
(-2/5) * (3/10) = (-2 * 3) / (5 * 10) = -6/50
So the answer is A. -6/50.
Multiply 4 by -5/8 write the answer as a mixed number in simplest form
A. -2 4/8
B.-5/2
C. -2 1/2
D. -10
To multiply 4 by -5/8, we multiply the whole number by the fraction:
4 * (-5/8) = -20/8
To simplify the fraction, we can reduce the numerator and denominator by dividing both by their greatest common divisor, which is 4:
-20/8 ÷ 4/4 = -5/2
So the answer is B. -5/2.
Multiply 6.5 by 0.3 write the answer as a decimal
A. 0.195
B. 1.86
C. 1.95
D. 19.5
To multiply 6.5 by 0.3, we multiply the two numbers:
6.5 * 0.3 = 1.95
So the answer is C. 1.95.
Multiply-19.3 by 6
To multiply -19.3 by 6, we multiply the two numbers:
-19.3 * 6 = -115.8
So the answer is -115.8.
Multiply -2 1/2 by -1 3/5 write the answer as a decimal
A. 4
B. -4
C. 2.86
D. -4.1
