Объяснение:

(15/14 - 12/25):23/35=15*25 - 14*12/( черта деления)14*25 *35/23= 375 - 168/( черта деления) 350 * 35/23= 207/350*25/23= 23*9*35/ ( черта деления) 35*10*23= 9\10

Answer 3

To simplify the expression (15/14 - 12/25):(23/35), we can follow the order of operations, which is typically expressed using the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's start by evaluating the subtraction inside the parentheses:

15/14 - 12/25 = (1525)/(1425) - (1214)/(2514) = 375/350 - 168/350

Now, let's find a common denominator for the fractions:

375/350 - 168/350 = (375 - 168)/350 = 207/350

Next, we can simplify the expression outside the parentheses:

207/350 ÷ 23/35 = (207/350) * (35/23)

Simplifying the multiplication of the fractions:

(207/350) * (35/23) = (207 * 35) / (350 * 23) = 7245/8050

The simplified expression is 7245/8050, which cannot be simplified further because there is no common factor between the numerator and denominator.
