2 1/4 plus what equals 5 3/4?
If we have an equation like 2 1/4 plus what equals 5 3/4, we need to find the missing value to solve the equation. To do this, we can convert the mixed numbers into improper fractions and then perform the addition.
Converting Mixed Numbers to Improper Fractions
Let's convert the mixed numbers into improper fractions:
- 2 1/4 = 9/4
- 5 3/4 = 23/4
Solving the Equation
Now, we can set up the equation:
9/4 + x = 23/4
To solve for x, we can subtract 9/4 from both sides of the equation:
x = 23/4 - 9/4
x = 14/4
x = 3 1/2
Answer
So, 2 1/4 plus 3 1/2 equals 5 3/4.
