Solve the equation w−5 2/5=3 1/4 .

1 answer

To solve the equation, we'll first convert the mixed numbers to improper fractions.

w - 5 2/5 = 3 1/4

In proper fraction form, 5 2/5 is equal to (5*5 + 2)/5 = 27/5.

And, 3 1/4 is equal to (3*4 + 1)/4 = 13/4.

So the equation becomes:

w - 27/5 = 13/4

Now, let's find a common denominator for the fractions on both sides of the equation. The least common multiple of 5 and 4 is 20.

Multiplying both sides of the equation by 20, we get:

20w - (20*27)/5 = (20*13)/4

Simplifying:

20w - 108 = 65

Adding 108 to both sides:

20w = 173

Finally, dividing both sides by 20:

w = 173/20

Therefore, the solution to the equation is:

w = 8 13/20
