Answer 2

2 3/10а - 1 2/3а= 23/10а-5/3а=69/30а-50/30а=19/30а

Если а=6, то 19/30*6=19/5=3 4/5

Answer 3

To evaluate the expression 2 3/10a - 1 2/3a when a = 6, we need to substitute the value of a into the expression and perform the arithmetic operations.

Let's start with the first term, 2 3/10a:

2 3/10a = 2 + 3/10a

Substituting a = 6:

2 3/10a = 2 + 3/10 * 6 = 2 + 18/10 = 2 + 9/5 = (10/5) + (9/5) = 19/5 = 3 4/5

Now let's move on to the second term, 1 2/3a:

1 2/3a = 1 + 2/3a

Substituting a = 6:

1 2/3a = 1 + 2/3 * 6 = 1 + 12/3 = 1 + 4 = 5

Finally, we can subtract the second term from the first term:

3 4/5 - 5 = (15/5) - 5 = 3 - 5 = -2

Therefore, when a = 6, the expression 2 3/10a - 1 2/3a is equal to -2.
