Answer 1

18/25 = 1.39

               .7 
5/8 =       .63


They are now in order from greatest to least.
Think of the amounts as money:
$1.39 
$0.70
$0.63

Answer 2

Answer:

$\frac{18}{25}$, $\frac{7}{10}$, $\frac{5}{8}$.

Step-by-step explanation:

We have been given that Nassim completed 18/25 of the math homework. Kara completed 0.7 of it. Debbie completed 5/8 of it. We are asked to list the numbers in order from greatest to least.

We will compare our given fraction by making a common denominator.

$0.7=\frac{7}{10}$

We know that least common multiple of denominator fractions: $\frac{18}{25}$, $\frac{7}{10}$ and $\frac{5}{8}$ is 200.

Let us make a common denominator.

$\frac{18*8}{25*8}=\frac{144}{200}$

$\frac{7*20}{10*20}=\frac{140}{200}$

$\frac{5*25}{8*25}=\frac{125}{200}$

Greatest to least:

$\frac{18}{25}$, $\frac{7}{10}$, $\frac{5}{8}$.
