1 2/3

Пошаговое объяснение:

1) 1 1/6-2/3=7/6-2/3=7/6-4/6=3/6

2)8*3/6=4

3)4: 1 1/5=4:6/5=4*5/6=10/3

4)5-10/3=15/3-10/3=5/3=1 2/3

Answer 2

To solve the expression 5-8*(1 1/6-2/3):1 1/5, we need to follow the order of operations, which is commonly remembered as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction). Let's break down the expression step by step:

First, let's simplify the fractions: 1 1/6 = 7/6 2/3

Now, let's calculate the expression within the parentheses: 1 1/6 - 2/3 = 7/6 - 2/3 = (72)/(62) - 4/6 = 14/12 - 4/6 = 14/12 - 8/12 = 6/12 = 1/2

Next, let's perform the multiplication: 8 * (1/2) = 8/1 * 1/2 = (8 * 1) / (1 * 2) = 8/2 = 4

Finally, let's perform the division: 4 : 1 1/5 = 4 / (6/5) = 4 * (5/6) = (45) / (16) = 20/6 = 10/3

Therefore, 5-8*(1 1/6-2/3):1 1/5 equals 10/3.
