Answer 1

1 2/3 - b = 5/6
b = 1 2/3 - 5/6
b = 1 4/6 - 5/6
b = 5/6

7/12 + a = 1 1/6
a = 1 1/6 - 7/12
a = 1 2/12 - 7/12
a = 7/12

y * 2/7 = 3/14
y = 3/14 : 2/7
у = 3/14 * 7/2
у = 3/4

6/7 : c = 3/14
с = 6/7 : 3/14
с = 6/7 * 14/3
с = 4

c + 1 1/3 = 3
с = 3 - 1 1/3
с = 1 2/3

a : 2/3 = 3/4
а = 3/4 * 2/3
а = 1/2

y - 5/6 = 1/3
у = 1/3 + 5/6
у = 2/6 + 5/6
у = 1 1/6

1 5/6 - y = 2/3
у = 1 5/6 - 2/3
у = 1 5/6 - 4/6
у = 1 1/6

x - 7/10 = 7/10
х = 7/10 + 7/10
х = 1 4/10
х = 1 2/5

1/3 +x= 1 1/6
х = 1 1/6 - 1/3
х = 1 1/6 - 2/6
х = 5/6

1 1/4 - b = 1/2
b = 1 1/4 - 1/2
b = 1 1/4 - 2/4
b = 3/4

1 1/2 * a = 6
a = 6 : 1 1/2 
а = 6/1 : 3/2
а = 6/1 * 2/3
а = 4

1 3/4 : x = 7
х = 1 3/4 : 7
х = 7/4 : 7/1
х = 7/4 * 1/7
х = 1/4

b * 5/7 = 1
b = 1 : 5/7 
b = 1/1 * 7/5
b = 7/5
b = 1 2/5

7/8 + a = 1 1/4
а = 1 1/4 - 7/8
а = 1 2/8 - 7/8
а = 3/8

y * 3/5 = 1/15
у = 1/15 : 3/5
у = 1/15 * 5/3
у = 1/9

1 2/3 : y = 5
у = 1 2/3 : 5
у = 5/3 : 5/1
у = 5/3 * 1/5
у = 1/3

Answer 2

To solve these equations, we'll need to use some basic algebraic operations. Here are the solutions to each of the given equations:

1. 1 2/3 - b = 5/6 First, we need to convert the mixed number to an improper fraction: 1 2/3 = 5/3 Then, we can solve for b by subtracting 5/6 from both sides and simplifying: 5/3 - b = 5/6 b = 5/3 - 5/6 b = 5/6

Therefore, the solution is b = 5/6.

2. 7/12 + a = 1 1/6 First, we need to convert the mixed number to an improper fraction: 1 1/6 = 7/6 Then, we can solve for a by subtracting 7/12 from both sides and simplifying: 7/12 + a = 7/6 a = 7/6 - 7/12 a = 7/12

Therefore, the solution is a = 7/12.

3. y * 2/7 = 3/14 To solve for y, we need to divide both sides by 2/7: y = (3/14) / (2/7) y = (3/14) * (7/2) y = 3/4

Therefore, the solution is y = 3/4.

4. 6/7 : c = 3/14 To solve for c, we need to invert the right-hand side and multiply both sides by it: 6/7 * (1 / (3/14)) = c 6/7 * (14/3) = c 2 * 2 = c c = 4

Therefore, the solution is c = 4.

5. c + 1 1/3 = 3 First, we need to convert the mixed number to an improper fraction: 1 1/3 = 4/3 Then, we can solve for c by subtracting 4/3 from both sides and simplifying: c + 4/3 = 3 c = 3 - 4/3 c = 5/3

Therefore, the solution is c = 5/3.

6. a: 2/3 = 3/4 To solve for a, we need to multiply both sides by 2/3: a = (3/4) * (2/3) a = 1/2

Therefore, the solution is a = 1/2.

7. y - 5/6 = 1/3 To solve for y, we need to add 5/6 to both sides and simplify: y = 1/3 + 5/6 y = 2/3

Therefore, the solution is y = 2/3.

8. 1 5/6 - y = 2/3 First, we need to convert the mixed number to an improper fraction: 1 5/6 = 11/6 Then, we can solve for y by subtracting 2/3 from both sides and simplifying: 11/6 - y = 2/3 y = 11/6 - 2/3 y = 5/6

Therefore, the solution is y = 5/6.

9. x - 7/10 = 7/10 To solve for x, we need to add 7/10 to both sides and simplify: x = 7/10
