Question

4 / 9 Б плюс 2 / 3 при Б равно 3 / 4​

Answer 1

Ответ:

Пошаговое объяснение:

$\frac{4}{9}b+\frac{2}{3}=\frac{4}{9}*\frac{3}{4}+\frac{2}{3}=\frac{1}{3}+\frac{2}{3}=\frac{3}{3}=1$

Answer 2

To solve the equation, we need to add the fractions on the left-hand side and set them equal to the fraction on the right-hand side.

Let's calculate the left-hand side:

4/9Б + 2/3

To add fractions with different denominators, we need to find a common denominator. The common denominator for 9 and 3 is 9. We'll convert the fractions:

(4/9)Б = (4/9) * (3/3)Б = (12/27)Б

(2/3) = (2/3) * (9/9) = (18/27)

Now we can add the fractions:

(12/27)Б + (18/27) = (12/27)Б + (18/27) = (12Б + 18)/27

So the equation becomes:

(12Б + 18)/27 = 3/4

To solve for Б, we can cross-multiply:

4 * (12Б + 18) = 3 * 27

48Б + 72 = 81

48Б = 81 - 72

48Б = 9

Б = 9/48

Simplifying the fraction:

Б = 3/16

Therefore, the value of Б that satisfies the equation is 3/16.
