b-1/4=3 1/2 solve the equation, and check the solution​

Sagot :

Answer:

b = 15/4 = 12/4 + 3/4 = 3  3/4 (in mixed number form)

Step-by-step explanation:

Let's start by converting the mixed number into an improper fraction so we can operate easily in the solving:

3  1.2 = 3 + 1/2 = 6/2 + 1/2 = 7/2

Now we solve the equation:

b - 1/4 = 7/2

add 1.4 to both sides

b = 7/2 + 1/4 = 14/4 + 1/4 = 15/4

Therefore, b = 15/4 = 12/4 + 3/4 = 3  3/4 (in mixed number form)
