Answer: W = 113/20
Step-by-step explanation:
What we know:
- We need to find the value of W
- The fractions need to be equivalent denominators
Process:
Set up equation W + 3/5 = 6 1/4
Expand W + 3/5 = 6*4+1 /4
Simplify W + 3/5 = 25/4
Common denominator W + 3*4/5*4 = 25*5 / 4*5
Simplify W + 12/20 = 125/20
Subtract -12/20 -12 /20
Solve W = 113/20
Answer: W = 113/20
Check:
By converting our answers into decimals, we can see if the sides are equal:
113/20 = 5.65
3/5 = 0.6
5.65 + 0.6 = 6.25
Does 6.25 = 6 1/4?
1/4 = 0.25
6 + 0.25 = 6.25
6.25 = 6.25
Therefore, W = 113/20 is the correct answer.
