Question

(4a-2/5)*5/4/(2a)-1/2

Answer 1

(4а-2/5)*5/4:(2а)-1/2=
5а-1/2:2а-1/2=5а/2а=2,5

Answer 2

To simplify the expression (4a - 2/5) * (5/4) / (2a - 1/2), you can follow these steps:

Step 1: Distribute the (5/4) to both terms inside the first set of parentheses: (5/4) * (4a) - (5/4) * (2/5)

This simplifies to: 5a - (1/2)

Step 2: Distribute the (1/2) to both terms inside the second set of parentheses: (5a - 1/2) / (2a - 1/2)

Now, the expression is: (5a - 1/2) / (2a - 1/2)

This is the simplified form of the expression.
