Is it true 50 x 5 = 100?

Yes or No? Why do you think so? Please share your reason.

​Please remember that:

​To easily change fractions to decimals, you must make sure the denominator is

​

​

               

Example:

​                The denominator is 2. Try and change it to 10.

                How? Let's put it this way: 2 x ____ = 10?

​

​Exactly! It's 5!!

That means the denominator must be multiplied by 5.

​Check the denominators:

​If you see the denominators are not 10 or 100 or 1000 please change it first.

​

​Here are some guidelines for you hopefully it can help you along the way...

​

​

​

​

​

​

200 x 5 = 1000

​Multiply the numerators:

​If you have multiplied the denominator, you need to multiply the numerator with the same multiplier.

​How to change fraction to decimal?

Put a decimal point at the back of the numerator.

​

​Example 1:

​=

If the denominator is 100, jump the decimal point 2 steps to the front.

​

​=

​=

If there is no number in front of where the

decimal point stops, just put zero.

​

​=
