Question

Which of the following numbers is the smallest:
15.377, 16.379, 15.396 and 15.378?

• A. 15.396
• B. 15.377
• C. 15.378
• D. 16.379

Answer 1

The correct option is B 15.377

The four numbers given are 15.377, 16.379, 15.396, and 15.378.

Let's analyse these numbers.

• Three numbers have 15 before the decimal point, while one of them has 16. So, 16.379 is not the smallest.
• If you look at the tenth place (after the decimal), all four numbers have the number 3.
• If you look at the hundredth place(after the decimal) of the remaining three numbers, Two of them have 7 and one has 9. So, 15.396 is not the smallest.
• But, at the thousandth place(after the decimal) of the remaining two numbers we have 7 and 8. of which 7 is the smallest.

Therefore, 15.377 is the smallest among the four.
