Question

1 4/5•4 4/6- 1 4/5•3 5/6+3 1/5=

Answer 1

Ответ:

71/10; 7.1

Пошаговое объяснение:

9/5 * 28/6 - 9/5 * 5/2+ 16/5

42/5-9/2+16/5

71/10

Answer 2

1 4/5 * 4 4/6 - 1 4/5 * 3 5/6 + 3 1/5 = (-1 7/10)

8 2/5 - 6 9/10 + 3 1/5

1 1/2 + 3 1/5

(-1 7/10)

Answer 3

To solve this expression, we can 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 this case, we have multiplication and subtraction:

1. First, let's simplify the multiplications:

   4/5 * 4 4/6 = 4/5 * 22/3 (convert the mixed number to an improper fraction) = (4 * 22)/(5 * 3) = 88/15

   1 4/5 * 3 5/6 = 9/5 * 23/6 (convert the mixed number to an improper fraction) = (9 * 23)/(5 * 6) = 207/10

2. Now, we can subtract these two results:

   88/15 - 207/10

To subtract these fractions, we need to have a common denominator, which in this case is 30.

So, we'll rewrite both fractions with a denominator of 30:

(88/15) * (2/2) = 176/30 (207/10) * (3/3) = 621/30

Now, the expression becomes:

176/30 - 621/30

3. Subtract the fractions:

   (176 - 621)/30 = -445/30

4. Simplify the fraction:

   -445/30 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 5.

   (-445 ÷ 5) / (30 ÷ 5) = -89/6

So, the result of the expression is -89/6.
