Point C is taken on line AB so that AC: BC = 4: 7. What can be the length of the segment BC if it is known that AB = 33

Point C is taken on line AB so that AC: BC = 4: 7. What can be the length of the segment BC if it is known that AB = 33 Point C is taken on the line AB so that AC: BC = 4: 7. What can the length of the segment BC be equal to if it is known that AB = 33.

Given:
AC: BC = 4: 7 (this is the ratio of the segments to each other)
AB = 33
Find: BC
Decision:
Let’s try to solve it in parts. There are (4 + 7) 11. Find how many are in one part.
1) 33: 11 = 3.
In total in one part 3. You can not look for what the segment AC is, but immediately find BC. Multiply 3 by 7.
2) 3 * 7 = 21.
Answer: 21.
