Answer: W = 113/20

Explanation:

What we know:

  • We need to find the value of W
  • 6 1/4 - 3/5 = 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.
