Question

1. arrange the numbers in descending orders (largest first):

a 5.35, 0.535, 53.5, 5.05, 3.55
b 0.7, 7.7, 7.07, 0.007, 7.007
c 1.5, 1.05, 1.005, 5.01, 5.001
d 7.53, 7.053, 5.73, 57.3, 75.3
e 2.12, 2.112, 21.12, 211.2, 0.2112

Explanation:

Step1: Analyze part a

Compare the numbers: 53.5, 5.35, 5.05, 3.55, 0.535. The largest is 53.5, then 5.35, then 5.05, then 3.55, then 0.535.
So order: \( 53.5, 5.35, 5.05, 3.55, 0.535 \)

Step2: Analyze part b

Compare: 7.7, 7.07, 7.007, 0.7, 0.007. Largest is 7.7, then 7.07, then 7.007, then 0.7, then 0.007.
Order: \( 7.7, 7.07, 7.007, 0.7, 0.007 \)

Step3: Analyze part c

Compare: 5.01, 5.001, 1.5, 1.05, 1.005. Largest 5.01, then 5.001, then 1.5, then 1.05, then 1.005.
Order: \( 5.01, 5.001, 1.5, 1.05, 1.005 \)

Step4: Analyze part d

Compare: 75.3, 57.3, 7.53, 7.053, 5.73. Largest 75.3, then 57.3, then 7.53, then 7.053, then 5.73.
Order: \( 75.3, 57.3, 7.53, 7.053, 5.73 \)

Step5: Analyze part e

Compare: 211.2, 21.12, 2.12, 2.112, 0.2112. Largest 211.2, then 21.12, then 2.12, then 2.112, then 0.2112.
Order: \( 211.2, 21.12, 2.12, 2.112, 0.2112 \)

Answer:

a. \( 53.5, 5.35, 5.05, 3.55, 0.535 \)
b. \( 7.7, 7.07, 7.007, 0.7, 0.007 \)
c. \( 5.01, 5.001, 1.5, 1.05, 1.005 \)
d. \( 75.3, 57.3, 7.53, 7.053, 5.73 \)
e. \( 211.2, 21.12, 2.12, 2.112, 0.2112 \)
