68 = r/4. Rearrange. r/4 = 68.
Cross multiply. r = 4*68 r = 272
That's it.
68=r/4 to get r alone you need to times it by its reciprical which is the opposite (do it to both sides example: 6/3=3/6
68=r/4 × 4/1 272=r
To solve the equation 68 = 4 r , multiply both sides by 4 to get r = 272 . This solution is verified by substituting r back into the original equation. Therefore, the final answer is r = 272 .
