Question

lance measured 0.485 liter of water. Angel measured 0.5 liter of water. lance said, "My beaker has more water than yours because my number has three decimal places and yours only has one." is lance correct?

Answer 1

No, Lance is not correct.

Further explanation:

If we compare the two decimal numbers then either they are less than, greater than or equal to each other.

For example:

There are two decimal numbers as,

$0.56{\text{ and 0}}{\text{.88}}$

Now, 0.88 is greater than 0.56 as the number after the decimal point is greater in 0.88 than 0.56.

It is given that Lance measured 0.485 litre of water.

Also, given that Angel measured 0.5 litre of water.

Lance claims that her beaker has more water than Angel’s breaker because her number has three decimal places and Angel’s only has one.

Step by step explanation:

Now, Lance has $0.485l$ of water and Angel has $0.5l$ of water.

The decimal number which has greater number after the decimal point, then that decimal number is greater than the other.

Therefore, Lance only has $0.485l$ of water whereas Angel has $0.5l$ of water in which Angel has more water than Lance.

Thus, Lance is wrong in analysing the water quantity.

Answer 2

Lance is absolutely not correct.

The fact that his beaker measures at 0.485 liter, and Angel’s at 0.5 does not significantly mean Lance beaker has more water than Angel.

Further Explanation

Mathematically, Angel’s beaker has more water than Lance because 0.5 liter is greater than 0.485 liter. Angel’s given measured liter can also be expressed as 0.500.

For instance:

Lance’s liter of water = 0.485

Angel’s liter of water = 0.500

Automatically, 0.500 is greater than 0.485

Furthermore, it can denoted that the above given question is a decimal number problem. A decimal is an improper fraction whose denominator can be in 10, 100, 1000 and so on. Examples of decimals are:

2/10                       = 0.2

2/100                     = 0.02

2/1000                  = 0.002

To understand decimals, one has to take note of placing number values.

To further highlight Lance’s wrong statement, it is important number values are evaluated. For instance

5 > 4

0.5 > 0.4

0.05 > 0.04

0.50 > 0.49 (This can also be expressed as 0.5 > 0.49; the zero after 5 is relatively insignificant, according to math theories)

Lance has a beaker that is measured at 0.485

Angel has a beaker that is measured at 0.5

From the above given illustration (0.50 > 0.49), it can be noted than 0.5 > 0.485 because 0.485 is lesser than 0.5 which can also be expressed as 0.500
