Question

5,2+2×(2+2,2)÷4+7,2=?

Answer 1

5,2+2*(2+2,2):4+7,2=14,5
1)2+2,2=4,2
2)4,2:4=1,05
3)2*1,05=2,1
4)5,2+2,1=7,3
5)7,3+7,2=14,5

Answer 2

To solve this mathematical expression, you need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

The expression you provided is:

5.2 + 2 × (2 + 2.2) ÷ 4 + 7.2

1. First, calculate the value inside the parentheses: 2 + 2.2 = 4.2
2. Next, perform the multiplication: 2 × 4.2 = 8.4
3. Then, divide the result by 4: 8.4 ÷ 4 = 2.1
4. Finally, perform the additions: 5.2 + 2.1 + 7.2 = 14.5

So, the solution to the expression is 14.5.
