6 out of 5 times a = B divided by 5 out of 4 = C divided by 7 out of 6, and a, B, C are not zero, sorted from small to large

6 out of 5 times a = B divided by 5 out of 4 = C divided by 7 out of 6, and a, B, C are not zero, sorted from small to large


1. Write the following equation according to the meaning of the question
6/5×A=B÷5/4=C÷7/6
2. Let's have three equations equal to one,
3. So: a = 5 / 6; b = 5 / 4; C = 7 / 6
4. Because: 5 / 6



Using the recursive equation: (2108-634 *?) / 56 = 15


(2108-634x)/56=15
Multiply both sides by 56
2108-634x=840
634x=2108-840
634x=1268
x=1268÷634
x=2
