Answer: 1320
Step-by-step explanation:
Given,
HCF of two numbers = 40
Product of two numbers = 52800
To find,
LCM of two numbers =?
Formula required,
HCF × LCM = product of two numbers
Calculation,
Using formula
→ HCF × LCM = product of two numbers
→ ( 40 ) × LCM = 52800
→ LCM = 52800 / 40
→ LCM = 1320
Therefore,
LCM of two numbers would be 1320.

 tons.
300 times.
Step-by-step explanation:
Last year, the world produced 3.5 billion tons of cement and that amount could increase by a billion tons by the year 2050.
So, the net production of cement by the year 2050 will be (3.5 + 1) = 4.5 billion tons i.e.  tons. (Answer)
 tons. (Answer)
Now, this amount is larger than  by
 by  times. (Answer)
