What is the suitable answer to fulfill the condition that supposed to be?

$$0.4\ \ ......\ \ 45\ \%$$  

Remember of Alligator Mouth !

Multiple Select

Look at the following numbers

Tick all the numbers that are equivalent to this fraction

$$\frac{3}{4}\$$  

• $$75\ \%$$  

• $$50\%$$  

• $$0.75$$  

• $$0.5$$  

Percentages

Take a look for this equivalent value

Remember Percentages is a part of 100 (always in hundredth)

Fraction

Decimals

​75 %

=

=

​0.75

=

Percentages are always in Hundredth​

Percentages, Decimals, and Fractions can placed on the same value​

​Remember that Percentage is a part of a hundred

​10 % or 0.1

​one-tenth became ten-hundredth, both of top and bottom are multiply by ten

​=

ten percent or zero point one

Draw

Write the missing number shown by the arrow as fraction !

How to Compare three or two different Formats?

The Formats are Percentages, Decimals, and Fraction, We already realize that We do equivalencing of three different formats into the same value, Which mean We try to make different formats into the same format. This idea lead us to compare easily when those formats convert into the same formats

What is the suitable answer to fulfill the condition that supposed to be?

$$90\ \%\ \ ......\ \ 95\ \%$$  

Remember of Alligator Mouth!

Multiple Choice

Which one is smaller between 0.9 and 95% ?

• $$0.9$$

• $$95\%$$

Draw

Remember the alligator mouth

Instead of convert into the percentage, you can directly do long division to find out the decimals number

For Example :​

You have to remember the multiplication very well

​Then we can compare easily those numbers in the same format which is 5.33 compare to 5.12

Multiple Choice

Which one is greater ?

• $$0.37$$  

• $$\frac{1}{3}$$  

The Concept of Comparing and Ordering

Look at the following numbers below. All of the numbers have different formats. In comparing and ordering concepts,​ All of the numbers must be in the same format before we compare or order them.

​or

​convert into the same format

​After the format is same, those numbers are ordering from smallest to largest as 29% 39% 40% 50%

Multiple Choice

Which one is greater between 17% and $$\frac{4}{25}$$  ?

• $$17\%$$  

• $$\frac{4}{25}$$  

Multiple Choice

Which one is greater between 0.086 and 86% ?

• $$86\%$$  

• $$0.086$$  

Multiple Choice

Which one is smaller between 20% and 0.02 

• 20%

• 0.02

Multiple Choice

Which one is smaller between 76% and 0.67 ?

• 76%

• 0.67

Multiple Choice

Which one is smaller between 37% and $$\frac{37}{50}$$  ?

• $$37\%$$  

• $$\frac{37}{50}$$  

Multiple Choice

Which one is greater between $$\frac{1}{3}$$  and 30 % ?

• $$\frac{1}{3}\$$  

• $$30\%$$  

Multiple Choice

Which one is greater between 50% and $$\frac{13}{50}$$  ?

• $$50\%$$  

• $$\frac{13}{50}$$  

Multiple Choice

Ordering from smallest to largest !

$$0.27\ \ \ \ \ \ \ \ \ \ \ 50\%\ \ \ \ \ \ \ \ \ \ \ \ \ \frac{1}{4}$$  

• $$\frac{1}{4}\ \ \ \ \ \ \ \ 50\%\ \ \ \ \ \ \ \ \ 0.27\ \ \ \ \ \ \ \ \ \ \$$  

• $$0.27\ \ \ \ \ \ \ \ \frac{1}{4}\ \ \ \ \ \ \ \ 50\%\ \ \ \ \ \ \ \ \$$  

• $$\frac{1}{4}\ \ \ \ \ \ \ \ 0.27\ \ \ \ \ \ \ \ \ \ \ 50\%$$  

Multiple Choice

Which one is greater ?

it need to do long division !

• $$5\ \frac{5}{6}\$$  fluid ounces

• $$5.6$$  fluid ounces

Draw

Ordering from smallest to largest !
