6 (d - f) + f

when d = 4 7/8 and f = 3 1/2

Given the data in the question;

- d = 4 7/8 =
- f = 3 1/2 =

- What is 6 (d - f) + f = ?

First, we convert the mixed fraction into an improper fraction

d = 4 7/8 = ( 8×4 + 7 )/8 = 39/8

f = 3 1/2 = ( 2×3 + 1 )/8 = 7/2

Now, we substitute the values of d and f into the expression.

234/8 - 42/2 + 7/2

234/8 - 168/8 + 7/2

33/4 + 7/2

33/4 + 14/4

47/4 or [tex]11\frac{3}{4}[/tex]

Therefore, the value of the expression 6 (d - f) + f when d = 4 7/8 and f = 3 1/2 is 47/4 or [tex]11\frac{3}{4}[/tex] .

Answer 2

6(4 7/8 - 3 1/2) + 3 1/2 = 47/4
You just have to plug in the numbers into the variables.
d = 4 7/8
f = 3 1/2
