Question

2-1:1/2+1/4:2+1:1/2+1/4​

Answer 1

Пошаговое объяснение:

1:1/2=2

1/4:2=0,25:2=0,125

2-2+0,125+2+0,25=2,375

Answer 2

To solve the given expression, follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The expression you provided is: 2 - 1 : 1/2 + 1/4 : 2 + 1 : 1/2 + 1/4

Step 1: Division 1/2 + 1/4 = (2/4) + (1/4) = 3/4

1 : 1/2 = 1 * 2 = 2

1/4 : 2 = (1/4) / 2 = 1/8

Step 2: Addition and Subtraction 2 - 3/4 + 1/8 + 1/2 + 1/4

Step 3: Find a common denominator for the fractions (in this case, 8): 2 - 6/8 + 1/8 + 4/8 + 2/8

Step 4: Combine the fractions and simplify: (2 - 6 + 1 + 4 + 2)/8 = 3/8

So, the simplified result of the expression is 3/8.
