Answer 3

To evaluate the expression 21а - 11b when a = 2/3 and b = 4/11, you just need to substitute the values of a and b into the expression and perform the arithmetic.

Here's the calculation step-by-step:

Given: a = 2/3 b = 4/11

Expression to evaluate: 21а - 11b

Substitute the values of a and b: 21 * (2/3) - 11 * (4/11)

Now, perform the arithmetic operations: 21 * (2/3) = 14 11 * (4/11) = 4

Now, the expression becomes: 14 - 4

Finally, subtract 4 from 14: 14 - 4 = 10

So, the value of the expression 21а - 11b when a = 2/3 and b = 4/11 is 10.
