Question

Which decimal represents the equation shown: (4 X 1,000) + (9 X 100) + 2^1 / 10?

a) 4900.205
b) 4090.025
c) 4900.250
d) 4009.025

Answer 1

To solve the given equation, calculate each component separately. After computing, we conclude that the correct answer is 4900.2, which corresponds to option a) 4900.205.

Step-by-step explanation:

To find which decimal represents the equation (4 x 1,000) + (9 x 100) + (21 / 10), we must calculate each part step by step:

1. (4 x 1,000) = 4,000,
2. (9 x 100) = 900,
3. 21 = 2, and when we divide by 10, we get 0.2.

Adding these numbers together:

4,000 + 900 + 0.2 = 4,900 + 0.2 = 4900.2

Now, let's match this result with the provided options:

a) 4900.205

b) 4090.025

c) 4900.250

d) 4009.025

The correct answer is a) 4900.2
