0.72
0.799
Answer:
Step-by-step explanation:
You'll find it easier to do this problem if you'd first rewrite the numbers so that they're all in the same numerical format:
A: 3/4 = 0.75
B: 0.72 = 0.72
C: 4/5 = 0.80
D: 0.799 = 0.799
E: 9/10 = 0.90
Now it's easy to see that B: 0.72 is the smallest of the 5 numbers and that 0.90 is the largest.
Arranged in ascending order, we have 0.72, 0.75, 0.799, 0.80, 0.90
Answer:
Because whole numbers are greater than 1 and any number greater than 1 multiplied by it self several times result in a greater number, but proper fractions are numbers less than 1, and a number less than 1 multiplied by it self several times result if a smaller number.
Explanation:
Whole numbers areraised to an exponent , means that such number is multiplied by itself (as many times and the exponent is).
Whole numbers are 1, 2, 3, 4, ....
Number 1 is a special case. When 1 is multiplied by it self the result is 1.
When other whole number (2, 3, 4, 5, ...) is multiplied by it self the result is a greater number. For example, 2 × 2 = 4, 3 × 3 = 9, and so on.
On the other hand, proper fractions, which are those whose numerator is less than the denominator, are less than one, and any number less than 1 multiplied by it self results in a smaller number.
For example: 1/2 × 1/2 = 1/4 or 0.5 × 0.5 = 0.25. This is always true for any proper fraction (a number less than 1).
