Question

Evaluate 1/4r + 7/12 when r = 7/12

Answer 1

Answer:

$\frac{35}{48}$

Step-by-step explanation:

Put the value of r in the equation.

$\frac{1}{4}$ × r + $\frac{7}{12}$  = $\frac{1}{4}$ × $\frac{7}{12}$ + $\frac{7}{12}$

Evaluate.

$\frac{1}{4}$ × $\frac{7}{12}$ + $\frac{7}{12}$ = $\frac{7}{48}$ + $\frac{7}{12}$

Make them have the same denominator by multiplying the denominator of the second fraction by 4 so their denominators are 48.

$\frac{7}{48}$ + $\frac{7}{12}$ = $\frac{7}{48}$ + $\frac{28}{48}$

Evaluate.

$\frac{7}{48}$ + $\frac{28}{48}$ = $\frac{35}{48}$
