Answer:
HCF of 112 and 46 = 2
Step-by-step explanation:
HCF/GCD/GCF all mean the same. They are the highest common factor of two or more numbers.
Step 1: First you extract all the 'Prime' factors of each number.
The ladders on the image show that you are dividing each number with the smallest prime number. You keep doing it till you reach 1 .
Step 2: Then you write the factors of each.
Step 3: You choose the common factors.
Step 4: Multiply the common factors (if any) and then you have your answer.

Answer:
Actual Height = 27.11 m
Step-by-step explanation:
Given:
Height of model rocket = 4.5 % of actual Height
Model Height = 1.22 m
To Find:
Actual Height of rocket = ?
Solution:
We have to Find the Actual Height of the rocket
Let actual height be x
Now it is given that
Height of model rocket = 4.5 % of actual Height
As we have the values so putting it in it becomes
1.22 = 4.5 % * x
it could be written as
Multiplying both sides by
it becomes
1.22* = x
= x
27.11 m =x
or
Actual Height = 27.11 m
