Answer 1

А)х+1,6=2 13/14
х=2 13/14-1 3/5
х=2 65/70-1 42/70
х=1 23/70
б)1 4/5+х=2,08
х=2,08-1,8
х=0,28
а)3,7-с=1 7/13
с=3 7/10-1 7/13
с=3 91/130-1 70/130
с=2 21/130
б)х-2 3/8=4,125
х=4,125-2,375
х=1,75
а)х-2 8/13=4,7
х=4 7/10+2 8/13
х=4 91/130+2 80/130
х=6 171/130=7 41/130
б)5,75-m=2 1/4
m=5,75-2,25
m=3,5
дальше в таком же духе

Answer 2

a) x + 1.6 = 2 + 13/14

To solve for x, we need to isolate it on one side of the equation.

First, we can simplify the right side of the equation: 2 + 13/14 = 28/14 + 13/14 = 41/14

Now the equation becomes: x + 1.6 = 41/14

To get rid of the 1.6 on the left side, we subtract it from both sides: x + 1.6 - 1.6 = 41/14 - 1.6

Simplifying further: x = 41/14 - 9/5

To subtract fractions, we need a common denominator. The least common multiple of 14 and 5 is 70.

Converting the fractions to have a denominator of 70: x = (41/14)*(5/5) - (9/5)*(14/14) x = 205/70 - 126/70

Subtracting the fractions: x = (205 - 126)/70 x = 79/70

Simplifying the fraction, we can write the final answer as: x = 1 9/70

b) 1 + 4/5 + x = 2.08

To solve for x, we need to isolate it on one side of the equation.

First, we can simplify the left side of the equation: 1 + 4/5 = 5/5 + 4/5 = 9/5

Now the equation becomes: 9/5 + x = 2.08

To get rid of the 9/5 on the left side, we subtract it from both sides: 9/5 - 9/5 + x = 2.08 - 9/5

Simplifying further: x = 2.08 - 1.8

Subtracting the decimals: x = 0.28

So the solution is x = 0.28

Please note that I have solved the first two equations. If you need help with the remaining equations, please let me know.
