Answer:

The value of the expression is -7/12.

None of the option is true.

Explanation:

To evaluate the expression 15/4 + (-4(1/3)) with the mixed fraction -4(1/3), we need to convert the mixed fraction into an improper fraction.

To convert the mixed fraction -4(1/3) to an improper fraction, we multiply the whole number (-4) by the denominator (3) and add the numerator (1).

The result becomes the new numerator, and the denominator remains the same.

So,

-4(1/3) can be rewritten as:

-(4 * 3 + 1) / 3

= -13/ 3.

Now, let's rewrite the expression with the correct term:

15/4 + (-13/3)

Next, let's find a common denominator for the fractions.

The least common multiple of 4 and 3 is 12.

Converting the fractions to have a denominator of 12:

15/4 is equivalent to (15/4) * (3/3) = 45/12.

-11/3 is equivalent to (-13/3) * (4/4) = -52/12.

Now, we can add the fractions:

45/12 + (-52/12)

= (45 - 52)/12

= -7/12.

Therefore,

The value of the expression is -7/12.

Find 15/4 + (-4(1/3))

a) 15/4

b) 11/3

c) 13/4

d) 7/6
