Nassim completed 18/25 of the math homework. Kara completed 0.7 of it. Debbie completed 5/8 of it. List the numbers in order from greatest to least.
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:
\(\frac{18}{25}\), \(\frac{7}{10}\), \(\frac{5}{8}\).
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:
\(\frac{18}{25}\), \(\frac{7}{10}\), \(\frac{5}{8}\).
