3x+4=28 because 3 times an unknown number was mentioned first and mentioned together so they will be together, increased by 4 is +4 and comes after, the result of is the same as equals so you put the equals sign and whatever number they gave after.
23:8 is the simplest form. However, you can put 5.75:2 or even 2.86/1 if you are looking for the absolute simplest
To multiply fractions, you just multiply across so you'd do:
3 × 2 = 6
4 × 3 = 12
The answer is 6/12, but it asks for the simplest form so you can simplify to 1/2. I hope this helps!
