Question

Simplify the expression 1/5 (9.8-3.3).

A. 2.6
B. 1.3
C. 1.2
D. 0.1
Its B but why is it B

Answer 1

Simplify the expression 1/5 (9.8 - 3.3):

Distribute the 1/5 to both terms inside the parentheses: (1/5) * 9.8 - (1/5) * 3.3

Simplify each term: 1.96 - 0.66

Add the two terms: 1.96 + (-0.66) = 1.3

So, the answer is B. 1.3.

The reason it's B is because when you distribute the 1/5 to both terms inside the parentheses, you get (1/5) * 9.8 - (1/5) * 3.3. Then, you simplify each term by multiplying 1/5 by 9.8 and 3.3, which gives you 1.96 and 0.66. Finally, you add the two terms together, 1.96 + (-0.66), which equals 1.3.

Answer 2

B 1.3

Step-by-step:

1/5 × (9.8 - 3.3) =

= (9.8 - 3.3) × 1/5

= 6.5 × 1/5

= 6.5/5

= 1.3

Step-by-step explanation:

You must do the subtraction first since the subtraction is in parentheses.

9.8 - 3.3 = 6.5

Now you multiply 6.5 by 1/5.

Multiplying by 1/5 is the same as dividing by 5.

6.5/5 = 1.3
