Question

1+2-3*4:5+6-7*8:9+10=?

Answer 1

Ответ:

467/45

Пошаговое объяснение:

1 + 2 - 3 × 4 ÷ 5 + 6 - 7 × 8 ÷ 9 + 10

1. 3 × 4 ÷ 5 = 12/5

2. 7 × 8 ÷ 9 = 56/9

↓

1 + 2 - 12/5 + 6 - 56/9 + 10 = 19 - 12/5 - 56/9 = 19 - 388/45 = 467/45

Answer 2

Ответ:

63

Пошаговое объяснение:

1+2-3*4/5+6-7*8/9+10=

=3-2,4+6-56/9+10=

=16,6-56/9=

=$\frac{16}{10}-\frac{56}{9}$=$\frac{144-560}{90}= -\frac{416}{90}$

Answer 3

Let's solve this expression step by step following the order of operations (PEMDAS/BODMAS - Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction):

1 + 2 - 3 * 4 ÷ 5 + 6 - 7 * 8 ÷ 9 + 10

Step 1: Multiplication and Division

• 3 * 4 = 12
• 7 * 8 = 56
• Now the expression becomes: 1 + 2 - 12 ÷ 5 + 6 - 56 ÷ 9 + 10

Step 2: Continue Multiplication and Division

• 12 ÷ 5 = 2.4
• 56 ÷ 9 ≈ 6.2222 (rounded to 4 decimal places)
• Now the expression becomes: 1 + 2 - 2.4 + 6 - 6.2222 + 10

Step 3: Addition and Subtraction

• 1 + 2 - 2.4 + 6 - 6.2222 + 10 = 10.3778

So, the result of the expression 1 + 2 - 3 * 4 ÷ 5 + 6 - 7 * 8 ÷ 9 + 10 is approximately 10.3778.
