Answer:

3) 4:5 4) 1:2

Step-by-step explanation:

We just have to simplify the fraction of the smaller side of the smaller figure over the larger side.

For number 3) 12/15 = 3*4 / 3* 5 = 4/5

For number 4) 7/14 = 8/16 = 1/2

Answer:

$\large\boxed{\large\boxed{\sqrt{3}$

Explanation:

You are comparing irrational numbers.

By inspection, i.e. at first sight you can only compare $\sqrt{3} \text{ }and\text{ } 2\sqrt{3}$ because they have the same radicand.

You can order: $\sqrt{3}$

You can introduce the 2 inside the radical by squaring it:

$2\sqrt{3}=\sqrt{2^2\times3}=\sqrt{12}$

Since 5 is between 3 and 12, you can order:

$\sqrt{3}$

Which is:

$\sqrt{3}$

You must know that π ≈ 3.14.

5 is less than 9 and the square root of 9 is 3; hence, $\sqrt{5}$ and $\sqrt{5}$

Now you must determine whether π is less than or greater than $\sqrt{12}$

Using a calculator or probing numbers between 3 and 4 you get $\sqrt{12} \approx3.46$

Hence, the complete order is:

$\sqrt{3}$

Explain how knowing that 5 divided by 8 =0.625 helps you write the decimal for 4 4/8.

ANTONII [103]

You have to divide 4 by 8 which = .5 and then u put the whole # before the decimal which will equal 4.5 , therefore knowing that 5 divided by 8 =0.625 does not help u write the decimal for 4 4/8 but the decimal for 4 4/8 is 4.5
