Question

12457*(-78): (-12)*87:(-42)*(-45)

Answer 1

$12457 \times ( - 78) \div ( - 12) \times 87 \div ( - 42) \times ( - 45) = \frac{211333005}{28}$

Answer 2

Let's break down the given expression step by step:

1. 12457 * (-78): 12457 multiplied by -78 equals -971,346.

2. (-12) * 87: -12 multiplied by 87 equals -1,044.

3. (-42) * (-45): When you multiply a negative number by another negative number, the result is positive. So, -42 multiplied by -45 equals 1,890.

Now, let's put it all together:

-971,346 : -1,044 : 1,890

To simplify this expression, you can divide each number by their greatest common divisor (GCD), which in this case is 3:

-971,346 / 3 = -323,782 -1,044 / 3 = -348 1,890 / 3 = 630

So, the simplified expression is:

-323,782 : -348 : 630
