Question:
Find the appropriate number: 21 : 24 = 7 : ......
Method of Solution:
Let the Required Number be x
21:24=7 : (x)
24×7=21x
168=21x
•°• x=168/21
x=8
Second Method: (2)
Express it in the form of Ratio by dividing (3), So we get
21:24 = 7: 8
Hence, Required NUMBER IS (8)

Answer:
21 : 24 = 7 : 8
Step-by-step explanation:
We're given two equivalent ratios in which one of the denominator is missing.
We know that, Equivalent ratios can be found by dividing or multiplying both the numerator and denominator by same number.
21 : 24 = 7 : 8.
This is simple mathematics, However we can solve by cross multiplication.
Let the unknown denominator be x.
21 : 24 = 7 : x
21 x = 24 × 7
x = 24/3
x = 8
Therefore, The missing number is 8.
