Answer 1

Пошаговое объяснение:

1,25-(1/3+0,5+0,25):(2/3+5/12)=0,25

1) 1/3+0,5+0,25=1/3+1/2+1/4=

=4/12+6/12+3/12=13/12

2) 2/3+5/12=8/12+5/12=13/12

3) 13/12:13/12=13/12×12/13=1

4) 1,25-1=0,25

Answer 2

To solve the given expression, let's break it down step by step:

1. Simplify the expression inside the parentheses: (1/3 + 0.5 + 0.25) = 1.08

2. Simplify the expression in the denominator: (2/3 + 5/12) = (8/12 + 5/12) = 13/12

3. Divide the numerator by the denominator: 1.25 / (13/12)

To divide by a fraction, we can multiply by its reciprocal. So, we can rewrite the expression as: 1.25 * (12/13)

Now, let's calculate the result: 1.25 * (12/13) = 15/13 ≈ 1.1538

Therefore, the value of the expression 1.25 - (1/3 + 0.5 + 0.25) / (2/3 + 5/12) is approximately 1.1538.
