Answer 2

Ответ:

24.44

Объяснение:

$(3.52 \div 1.1 + 6.2) \times (7 \times \frac{1}{5} - 4.6) =( 3.2 + 6.2) \times ( \frac{36}{5} - \frac{23}{5} ) = 9.4 \times \frac{13 }{5} = \frac{47}{5} \times \frac{13}{5} = \frac{611}{25} = 24 \times \frac{11}{25} = 24.44$

Answer 3

To solve this expression, you should follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction) to ensure the correct result.

Let's break it down step by step:

1. First, calculate the values inside the parentheses/brackets:

   • Inside the first set of parentheses: 3.52 ÷ 1.1 + 6.2
     • 3.52 ÷ 1.1 = 3.2
     • 3.2 + 6.2 = 9.4

2. Inside the second set of parentheses, convert the mixed number to a fraction:

   • 7 1/5 = 36/5

3. Subtract 4.6 from the fraction:

   • 36/5 - 4.6 = (36/5) - (23/5) = 13/5

4. Now, multiply the results from step 1 and step 3 together:

   • 9.4 × (13/5)

To multiply a decimal by a fraction, you can convert the decimal to a fraction by putting it over 1:

• 9.4 = 9.4/1

Now, multiply the fractions:

• (9.4/1) × (13/5)

To multiply fractions, simply multiply the numerators together and the denominators together:

• (9.4 × 13) / (1 × 5)

Calculate the products in the numerator and denominator:

• (122.2) / (5)

Finally, divide the numerator by the denominator:

• 122.2 / 5 = 24.44

So, the final result is approximately 24.44.
