Can anyone help me with this math please I will give brainlist
alexandr402 [8]

Answer:

4.5 > 4.420

0.67 < 0.8

0.82 = 0.820

62.4 > 6.24

0.13, 0.3, 0.303, 0.32

0.08, 0.8, 0.82, 8.2

24.54, 24.4, 24.304, 24.24

6.5, 6.25, 6.05, 6.007

Step-by-step explanation:

The most useful way to compare fractions is to add extra zeros at the end.

For example, 0.67 ___ 0.80.

0.80 is obviously bigger than 0.67.

In 24.4, 24.54, 24.304, 24.24, you can add extra zeros as well.

24.400, 24.540, 24.304, 24.240 (This makes it much easier to group the numbers, whether from largest to smallest or smallest to larger).

**REMEMBER TO REMOVE THOSE ZEROS AFTER FINDING YOUR FINAL ANSWER**

\bf \begin{cases} x-2y=-7\\ x-y=9\implies \boxed{x}=9+y \end{cases} \\\\\\ \stackrel{\textit{substituting \underline{x} in the first equation}}{\boxed{9+y}-2y=-7}\implies -y=-16 \\\\\\ y=\cfrac{-16}{-1}\implies y=16\\\\ -------------------------------\\\\ \stackrel{\textit{and substituting \underline{y} in the first equation}}{x-2(16)=-7}\implies x-32=-7\implies x=25 \\\\\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~(\stackrel{x}{25}~~,~~\stackrel{y}{16})
