Question

1) 4-2 8/15, 3 5/9+ 4 11/18 2)( x- 5 3/4) •2+9 7/11=12

Answer 1

1) 4-2 8/15= 4–16/15= 44/15.

3 5/9+ 4 11/18= 5/3+2•11/9= 5/3+22/9= 37/9.

2) ( x- 5 3/4) •2+9 7/11=12

( x- 5 3/4) •2+63/11=12

2x–15/2+63/11=12

2x–39/22= 12

2x= 12+39/22

2x= 303/22

x= 303/24

Answer 2

Пошаговое объяснение:

1)

4 - 2 8/15 = 3 15/15 - 2 8/15 = 1 7/15,

3 5/9 + 4 11/18  = 3 10/18 + 4 11/18 = 7 21/18 = 8 3/18 = 8 1/6,

2)

( x - 5 3/4) * 2 + 9 7/11 = 12,

(х - 5 3/4) * 2 = 12 - 9 7/11,

(х - 5 3/4) * 2 = 11 11/11 - 9 7/11,

(х - 5 3/4) * 2 = 2 4/11,

х - 5 3/4 = 2 4/11 : 2,

х - 5 3/4 = 26/11 * 1/2,

х - 5 3/4 = 26/22,

х = 26/22 + 5 3/4,

х = 26/22 + 23/4,

х = 52/44 + 253/44,

х = 305/44,

х = 6 41/44

Answer 3

Let's solve the given expressions step by step:

1. $4 - \frac{2}{8} \frac{15}{3} + \frac{5}{9} + \frac{4}{11} \frac{18}{2}$

Step 1: Simplify the fractions first. $4 - \frac{2}{8} = 4 - \frac{1}{4} = \frac{16}{4} - \frac{1}{4} = \frac{15}{4}$

Step 2: Add the whole numbers and the simplified fractions. $\frac{15}{4} + \frac{5}{9} + \frac{4}{11} = \frac{15 \times 9}{4 \times 9} + \frac{5 \times 4}{9 \times 4} + \frac{4 \times 2}{11 \times 2}$ $= \frac{135}{36} + \frac{20}{36} + \frac{8}{22}$ $= \frac{135 + 20 + 8}{36}$ $= \frac{163}{36}$

Answer to 1) is $\frac{163}{36}$ or approximately $4.5278$.

2. $(x - \frac{5}{4}) \cdot 2 + \frac{9}{7} + \frac{7}{11} = 12$

Step 1: Distribute the 2 on the left-hand side. $2x - 2 \cdot \frac{5}{4} + \frac{9}{7} + \frac{7}{11} = 12$

Step 2: Simplify the fractions. $2x - \frac{10}{4} + \frac{99}{77} = 12$

Step 3: Further simplify the fractions and combine like terms. $2x - \frac{5}{2} + \frac{99}{77} = 12$

To continue further and solve for the value of $x$, we need more information about the equation or any additional constraints on $x$.

If you have more information about the equation or constraints, please provide them so that we can proceed with the solution. Otherwise, the equation is not solvable with the given information.
