Question

4*7/12*(-1*3/11)-(-1*1/15)*(-45/64)

Answer 1

1) 4 7/12 • ( - 1 3/11 ) = 55/12 • ( - 14/11 ) = - 35/6 = - 5 5/6

2) ( - 1 1/15 ) • ( - 45/64 ) = ( - 16/15 ) • ( - 45/64 ) = 3/4

3) - 5 5/6 - 3/4 = - 5 10/12 - 9/12 = - 5 19/12 = - 6 7/12

Answer 2

Let's break down the expression step by step:

1. First, let's calculate the products within parentheses: -1 * 3/11 = -3/11 -1 * 1/15 = -1/15

2. Now, calculate the division: 4 * 7/12 = 28/12 = 7/3

3. Next, calculate the second division: -45/64

Now, we can substitute these values back into the original expression and perform the calculations:

(7/3) * (-3/11) - (-1/15) * (-45/64)

Now, multiply the fractions:

(7/3) * (-3/11) = -21/33 = -7/11

(-1/15) * (-45/64) = 45/960 = 3/64

Finally, subtract the second product from the first:

-7/11 - 3/64

To subtract these fractions, we need a common denominator, which is 11 * 64 = 704.

(-7/11) * (64/64) = -448/704

(3/64) * (11/11) = 33/704

Now, subtract:

(-448/704) - (33/704) = -481/704

So, the result of the expression is -481/704.
