Here are four numbers.

0.43 3 7 43.8% 7 16

Write these numbers in order of size.
Start with the smallest number

express all as decimals, and it's easy

0.43 = 0.430
43.8% = 0.438
and so on
The integers, of course, are easy, and they are greater than any of the fractions

ahhh very nice my all of my 32 children will finally know math thank you oobleck love from china saoirse

To order these numbers from smallest to largest, we need to first understand the form of each number.

0.43 is a decimal number.
3 is a whole number.
7 16 seems to be a fraction.
43.8% is a percentage.

To order these numbers correctly, we need to convert them to a consistent form, such as decimals or fractions.

Let's start by converting the fraction 7 16 to a decimal:

To convert a fraction to a decimal, we divide the numerator (7) by the denominator (16):

7 ÷ 16 = 0.4375

So, the fraction 7 16 can be written as a decimal as 0.4375.

Now let's convert the percentage 43.8% to a decimal:

To convert a percentage to a decimal, we divide it by 100 (or move the decimal point two places to the left):

43.8 ÷ 100 = 0.438

So, the percentage 43.8% can be written as a decimal as 0.438.

Now, let's order the numbers from smallest to largest:

The numbers in decimal form are: 0.43, 3, 0.4375, 0.438

Ordering these numbers from smallest to largest, we get:

0.43, 0.4375, 0.438, 3

Therefore, the numbers, in order of size starting with the smallest, are: 0.43, 0.4375, 0.438, 3.
