6/25 equals D Over 30 what does D equals
Rufina [12.5K]
Your equation is 6/25 = d/30. to solve this equation we have to get d by itself! to do this, you have to multiply each side by 30 since d is being divided by thirty. d/30 x 30 = d, 6/25 x 30 =  7.2, or 7 2/10

therefore, d = 7.2
hope this helps!
