A) -10/507
B) 10/507
C) -10/273
D) 10/273

Answer 1

To evaluate the expression -10(-4/39)(-3/16), multiply the fractions and then the result by -10. To evaluate the expression -10 ÷ (20/7), divide -10 by the fraction 20/7.

Step-by-step explanation:

To evaluate the expression -10(-4/39)(-3/16), we can simplify it step by step:

1. Multiply -4/39 by -3/16: (-4/39) * (-3/16) = 12/624 = 1/52
2. Then, multiply 1/52 by -10: (1/52) * (-10) = -10/52 = -5/26

So, the value of the expression -10(-4/39)(-3/16) is -5/26.

To evaluate the expression -10 ÷ (20/7), we can simplify it as follows:

1. Divide -10 by 20/7: -10 / (20/7) = -10 * (7/20) = -70/20 = -7/2

Therefore, the value of the expression -10 ÷ (20/7) is -7/2.
