What is 4 1/3 + 8 1/4

12 7/12

4 (1/3) + 8 (1/4) (Add the whole numbers together)

= 12 [(1/3) + (1/4)] (Find the LCD and multiply the numerators and denominators by the amount that will get you the LCD*)

= 12 [(4+3)/12]

= 12 (7/12)

*LCD = 12

(1/3) · 4 = 4/12

(1/4) · 3 = 3/12

the 3rd option is right

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
