Identify the descending numerical order of these fractions, and decimals, 0.733 and 0.923 and 1 2/5, 17/20 and 15/18

1 answer

To identify the descending numerical order of these fractions and decimals, we can convert everything to decimals and then arrange them in descending order.

Converting the given fractions to decimals:
1 2/5 = 1 + (2/5) = 1 + 0.4 = 1.4
17/20 = 0.85
15/18 = 0.8333...

So now we have the following decimals:
0.733, 0.923, 1.4, 0.85, 0.8333...

Arranging them in descending order:
1.4, 0.923, 0.85, 0.8333..., 0.733

Therefore, the descending numerical order is:
1 2/5, 0.923, 17/20, 15/18, 0.733
