Answer 3

A) -12/35 * 15/16

To solve this, we first multiply the numerators together and the denominators together:

(-12 * 15) / (35 * 16)

This gives us:

-180 / 560

Now we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 20:

-9 / 28

So the result of the first expression is -9/28.

B) 13/28 : (-11.14)

To divide a fraction by a number, we can multiply the fraction by the reciprocal of the number:

13/28 * (-1/11.14)

This gives us:

-13/28 * (1/11.14)

Now we can multiply the numerators together and the denominators together:

(-13 * 1) / (28 * 11.14)

This gives us:

-13 / 311.92

So the result of the second expression is -13/311.92.
