Question

Which is bigger 1.643 or 1.9

Answer 1

1.9 is bigger than 1.643

Answer 2

Answer: 1.9

Step-by-step explanation

Think of 1.9 as 1.900

This is so 1.643 and 1.900 have the same number of digits after the decimal point.

Both numbers start with a "1" and have a decimal point. So we compare the stuff after the decimal point.

900 > 643, so 1.900 > 1.643 which leads to 1.9 > 1.643
