# "How much reduction" or "How would reduction"

I have a method A, which is used to reduce the computation of difficult models. I would like to say that using this method will provide a great reduction in the computation of the model.

Method A reduces the computation of the model to the half. Then, we can see how much the great reduction of the model computation will be introduced using method A.

or

Method A reduces the computation of the model to the half. Then, we could see how would the great reduction of the model computation will be introduced using method A.

I would like to know, is it correct to use much with the word reduction or would, and why?

• @MichaelRybkin, No, I just need to know is it correct to use "much" or "would" with the word "reduction". As I understand "much" is used with an uncountable noun. Jan 16, 2019 at 5:27

Both versions of the passage are awkward.

The phrase to the half is unidiomatic as you've used it. Rather than say to the half, we generally say in half.

I suggest simplifying it into something briefer—which also dispenses with your word choice.

Method A greatly simplifies the computation of the model, reducing its complexity in half.

That aside, there is no reason to have to choose between much and would.

You can say something like this:

We can see how much of a reduction in the computation of the model would be achieved by using method A.

Here, reduction is uncountable. That does not mean that it's not measurable.

Consider this:

"How much flower should I use?"
"One cup."

Flower here is uncountable. It's a mass noun. But you can still measure it.

In the same vein:

"How much of a reduction will it be?"
"50 percent."

• Thank you for your answer. But as I understand much is only used with uncountable. Jan 16, 2019 at 5:37
