My math homework says this: what is 1/10+13/18?

First, find the common denominator, which would bee 90 So,

1/10 = 9/90 
13/18 = 65/90
65       9            74       37
 +    =   =
90       90         90      45

To add fractions all you do is add the LCD and then combine it.

The answer to your question is:

37/45

Step 1: Simplify 13/18

Equation at the end of step 1: 1/13 + 10/18

Step 2: Simplify 1/10

Equation at the end of step 2: 1/10 + 13/18

Find the LCD: It is 90

The calculate the Multipliers: The left is 9 and the right is 5

Then make Equivalent Fractions: Left is 9/90 and the right is 13 * 5/90

Then adding the fraction that have a common denominator: 9+13*5/90 = 37/45

Final Answer 37/45

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)

I’m not sure what sujevtbis this
