Step-by-step explanation:
Given fractions ,
,
.
We need to list them from least to greatest.
In order to arrange them from least to greatest, we need to find the least common denominator of ,
,
.
We have 3, 6 and 5 in denominators.
Least common multiple of 3, 6 and 5 is = 30, because 30 is least number that can be divided by all three number 3, 6 and 5.
Let us covert each denominator as 30.
Multiplying first fraction by 10 in top and bottom, we get
Multiplying first fraction by 5 in top and bottom, we get
Multiplying first fraction by 6 in top and bottom, we get
Now, we can check
is the smallest,
is greater and
is the greatest.
Therefore, we can arrange fractions
Writing original fractions in place of equivalent fractions, we can write
,
and
.
Therefore, the order the amounts of paint from least to greatest is:

Answer:
% area of the shaded region = 33%
Step-by-step explanation:
Radius of the middle circle = 7 cm
Radius of the inner circle = 4 cm
Area of the middle circle = πr²
= π(7)²
= 49π
Area of the inner circle = π(4)²
= 16π
Area of the shaded region= 49π - 16π
= 33π
Area of the outermost circle = π(10)²
= 100π
% area of the shaded region =
=
= 33%
Therefore, area of the shaded region is 33% of the complete logo.
