Question

1)(1/12+1/6):(3/8- 1/4)2)(1-4/9):(1/3-1/4​

Answer 1

Ответ:

1) 2

2) 6 2/3

Пошаговое объяснение:

=======================

1) (1/12 + 1/6) : (3/8 - 1/4) = (1/12 + 2/12) : (3/8 - 2/8) = 3/12 : 1/8 = 3/12 * 8/1 = 2/1 = 2

2) (1 - 4/9) : (1/3 - 1/4)= (9/9 - 4/9) : (4/12 - 3/12) = 5/9 : 1/12 = 5/9 * 12/1 = 20/3 = 6 2/3

=======================

Answer 2

Let's solve these two expressions step by step:

1. (1/12 + 1/6) / ((3/8) - (1/4))

First, simplify the fractions inside the parentheses:

1/12 + 1/6 = 2/12 + 4/12 = 6/12 = 1/2

Now, simplify the denominator:

(3/8) - (1/4) = (3/8) - (2/8) = 1/8

Now, we can divide the numerator by the denominator:

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

So, the result of the first expression is 4.

2. (1 - 4/9) / ((1/3) - (1/4))

First, simplify the fractions inside the parentheses:

1 - 4/9 = 9/9 - 4/9 = 5/9

Now, simplify the denominator:

(1/3) - (1/4) = (4/12) - (3/12) = 1/12

Now, we can divide the numerator by the denominator:

(5/9) / (1/12) = (5/9) * (12/1) = (5/9) * 12 = 60/9 = 20/3

So, the result of the second expression is 20/3.
