Question

Combining like terms with rational coefficients
7/8m+9/10-2m-3/5

Answer 1

Ah yes, one of my favorite topics.

Step 1: Which ever fraction comes first, you will solve it first. For this question, focus on doing
`(7)/(8)m-2m` first. Afterwards, do
`(9)/(10)-(3)/(5)`

Step 2: First one equals to 1.125. Next, find the LCD (lowest common dominator, which is 10).
`(9)/(10) -(6)/(10)=(3)/(10)`

Step 3: 1.125+3/10
