Question

4/15*(-5/8)+3/4*(-4/9)

Answer 1

4/15 × ( - 5/8 ) + 3/4 × ( - 4/9 ) = - 1/3 × 1/2 - 1/3 = - 1/6 - 1/3 = - 1/2 = - 0,5

Answer 2

Сокращаем.
1/3*-1/2 + 1/1*1/3 =  -1/6 + -1/3 = (-1-2)/6 = -3/6 = -1/2

Answer 3

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Now, let's solve the expression step by step:

1. Calculate the first term: 4/15 * (-5/8) = -20/120 = -1/6

2. Calculate the second term: 3/4 * (-4/9) = -12/36 = -1/3

3. Add the results of the two terms: -1/6 + (-1/3) = -1/6 - 2/6 = -3/6 = -1/2

So, the final answer is -1/2.
