Question

The fourth proportional of 5,6,10 is?​

Answer 1

Answer:

12

this is because since 5:6 is one proportion and the other proportion starts with 10, we know that 5 into 2 is 10. so the second proportion that is 6 needs to be multiplied with 2 to get the 4th proportion. 6*2 is 12. thus, 12 is the fourth proportion.
