Answer:
14
Explanation:
It can be easily calculated by dividing 40 by 100 and multiplying the answer with 35 to get 14.
How to do it
Since you are dividing by 100, you would move the decimal, which is at end of every number backwards two times since 100 has two zeroes. You'll get 0.4 because if you move the decimal backwards once you'll get 4.0, move it back the 2nd time you'll get 0.4. Then after you get 0.4, you will multiply it by 35 , which will give you your answer of 14.
