how do I solve this proportion?
Answer (3)
x 3 = 10 7 ; D : x = 0 cross m u lt i pl y : 7 ⋅ x = 3 ⋅ 10 7 x = 30 / : 7 x = 7 30 x = 4 7 2
Okay this should be simple. So take 10 times 3. Because those are diagnal to eachother. 10*3 = 30. Now take 30 divided by 7. 30/7 = 4.28 and rounded would be just 4.2. That's your answer! Hope i helped!
To solve the proportion x 3 = 10 7 , cross multiply to get 30 = 7 x , then isolate x by dividing by 7 to find x = 7 30 , or as a mixed number, 4 7 2 . Always check your answer by substituting it back into the original equation to ensure both sides are equal.
