Question

1)4/8-9/1+392)8/4+2/1-7/1​

Answer 1

Ответ:

4/8-9+39= 4/8+30=61/2

2+2-7=-3

Answer 2

Let's solve each of these expressions step by step:

1. (4/8) - (9/1) + (39/2)

First, simplify the fractions:

• 4/8 simplifies to 1/2 because both the numerator and denominator have a common factor of 4.
• 9/1 is already in its simplest form.

Now, calculate each part:

• 1/2 - 9/1 = 1/2 - 9 = -8.5
• -8.5 + 39/2 = -8.5 + 19.5 = 11

So, the result of the first expression is 11.

2. (8/4) + (2/1) - (7/1)

Again, simplify the fractions:

• 8/4 simplifies to 2 because both the numerator and denominator have a common factor of 4.
• 2/1 is already in its simplest form.
• 7/1 is also already in its simplest form.

Now, calculate each part:

• 2 + 2 - 7 = 4 - 7 = -3

So, the result of the second expression is -3.
