Question

3 12/36⋅(2/5−4/12)−3:1 1/2.​

Answer 1

$3\frac{12}{36}*(\frac{2}{5} -\frac{4}{12})-3:1\frac{1}{2}=\frac{4}{3}*(\frac{6}{15}-\frac{5}{15})-3*\frac{2}{3}=\frac{4}{3}*\frac{1}{15}-2=\frac{4}{45}-\frac{90}{45}=-\frac{86}{45}=-1\frac{41}{45}$

Answer 2

Ответ:

$- 1 \frac{7}{9}$

Answer 3

To simplify the expression, you should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right). In your expression, there are no parentheses or exponents, so we'll proceed with multiplication, division, and finally, subtraction:

1. Start with the multiplication and division from left to right:

   3 * (12/36) * (2/5 - 4/12) - 3 ÷ (1 1/2)

2. Simplify the fractions:

   3 * (1/3) * (2/5 - 1/3) - 3 ÷ (1 1/2)

3. Continue to simplify the fractions within the parentheses:

   3 * (1/3) * (6/15 - 5/15) - 3 ÷ (1 1/2)

4. Subtract the fractions within the parentheses:

   3 * (1/3) * (1/15) - 3 ÷ (1 1/2)

5. Multiply and divide:

   (3/3) * (1/15) - 3 ÷ (3/2)

6. Simplify further:

   1/15 - 3 ÷ (3/2)

7. Divide 3 by (3/2):

   1/15 - 3 * (2/3)

8. Multiply 3 by (2/3):

   1/15 - 2

9. To subtract fractions, you need a common denominator:

   (1/15) - (30/15)

10. Subtract:

(1/15) - (30/15) = -29/15

So, the simplified value of the expression is -29/15 or approximately -1.9333.
