Let x represent Seth's age, and x+28 represent his mother's age. When she is five times Seth's age, then:
5x = x+28
Solve for x:
5x = x+28
5x-x=28
4x=28
x=7
So, Seth will be seven years old, and his mother will be 7+28 = 35 years old when she is five times as old as him.
Twenty eight = 28
one hundred twenty-eight
Twenty-two and eight tenths.
Actually, the answer is "eight twenty-first-ths"
Twenty-eight quindecillion.
Twenty thousand eight hundred
The Great Twenty-Eight was created in 1982.
It is eight and twenty one thousandths.
The least common multiple of four, twenty eight, and twenty is 140.
2.5 (one tenth) x 8 = twenty
Eight times twenty-five times twenty-three is equal to 4,600.
On average, in the entire world about twenty eight thousand people will have the same birthday as one another. In a room full of people, there should be two people who have the same birthday.
