Well there are several ways to do this:

2(1)+2(3/4)

2+6/4

2+1+2/4

2+1+1/2

3+1/2

3 1/2

...

You could also change the mixed number to an improper fraction...

rule: a b/c=(ac+b)/c

2(1 3/4)

2(7/4)

14/4 simplify

7/2 which can be changed back to a mixed number

(6+1)/2

6/2+1/2

3+1/2

3 1/2

or you could just represent your mixed fraction as a decimal

2(1.75)

3.5

To find out what 1 and 3/4 times 2 is, we need to find out a way to make it much more simple and then answer it.
A quick way to answer this in a few steps is to:
1.) convert the fraction into decimal.
To do this, we need to divide 100 by our denominator (the number on the bottom of a fraction). Let's try it.
100 / 4 = 25.
For every 1/4, it adds 25.
Since we have 3/4, multiply 3 by 25.
You get 75, but it is not whole.
2.) Put your quotient into decimal form by putting it as 0.## (if we divided 100 by a smaller number).
Your number for 3/4 is 0.75.
Since we have a whole number (1), put it in the single-digit place.
(#.00)
1.75 is your fraction into decimal form.
Now, we need to multiply 1.75 by 2.00.
2.00 x 1.75 = 3.5
Your product is 3.5.
I hope this helps!
