15*(1+1/3-1/5)ПЖЖЖЖЖЖЖЖЖЖЖЖЖЖЖЖЖЖЖЖ ​

Answer 1

Ответ:

17

Пошаговое объяснение:

15*(1+1/3-1/5)=

1 способ:

= 15*1 + 15*1/3 - 15*1/5 =

= 15 + 15/3 - 15/5 =

= 15 + 5 - 3 = 20 - 3= 17

2 способ:

= 15*(1 + (1*5)/(3*5) - (1*3)/(5*3)) =

= 15*(1 + 5/15 - 3/15)=

= 15*(1 + (5-3)/15)=

= 15*(1 + 2/15) =

= 15*(15/15 + 2/15)=

= 15* ((15+2)/15) =

= 15*17/15 = 17

Answer 2

To calculate the expression, you can follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break down the expression step by step:

1. Calculate inside the parentheses:

1 + 1/3 - 1/5 = (15/15) + (5/15) - (3/15) = (15 + 5 - 3)/15 = 17/15

2. Now, multiply by 15:

15 * (17/15) = 17

So, the result of the expression is 17.
