Answer:Solution:
5 : 6 = 5/6
20 : ____ = 20/____
Since the ratios form a proportion.
Therefore, 5/6 = 20/____
To get 20 in the numerator, we have to multiply 5 by 4. So, we also multiply the denominator of 5/6, i.e. 6 by 4
Thus, 5/6 = 20/6 × 4 = 20/24
Hence, the required numbers is 24

Answer: 25 30 30 a
Use proportion
25× a = 30×30
a = 30×30/25 =36
a 24 24 64
Use proportion
64×a = 24×24
a= 24×24/64 =9
36 42 42 a
a×36 =42×42
a=42×42/36=49
Step-by-step explanation:
The third proportional of two numbers a and b is defined to be that number c such that a : b = b : c. So you want to find a number c such that25:30= 30 : a. That number is 36
