Question

(1/5х-9/10)+(7/10х-4/5)

Answer 1

(1/5х-9/10)+(7/10х-4,5)=1/5х-9/10+7/10х-4,5=2/10х-9/10+7/10х- 4 5/10=9/10х-5 4/10=0,9х-5,4

Answer 2

To simplify the expression (1/5x - 9/10) + (7/10x - 4/5), you'll want to find a common denominator and then combine like terms. Here's how you can do it step by step:

Step 1: Find a common denominator for the fractions in both terms. In this case, the common denominator is 10x, as it's the least common multiple of 5x and 10x.

Step 2: Rewrite each fraction with the common denominator:

(2/10x - 9/10) + (7/10x - 8/10)

Step 3: Combine like terms by adding or subtracting the numerators:

(2/10x + 7/10x) - (9/10 + 8/10)

Step 4: Add or subtract the numerators with the same denominator:

(9/10x) - (17/10)

Now you have a simplified expression:

(9/10x) - (17/10)

This is the simplified form of the given expression.
