To find the ARITHMETIC mean of 4 and 10, you add them up and then divide by n number of values: (4+10)/2 = 7 To find the GEOMETRIC mean, you multiply 4 and 10, and then find the nth root: the square root of 40 is 6.32 (to 3 significant figures).
Geometric mean of 32 and 50 = sqrt(32*50) = sqrt(1600) = 40
The least common multiple is the smallest positive number that is a multiple of two or more numbers. 8: 16, 24, 32, 40 10: 10, 20, 30, 40 The least common multiple for 8 and 10 is 40.
Well, honey, to rewrite 5/8 and 7/10 with the least common denominator, you first need to find the least common multiple of 8 and 10, which is 40. Then, you can rewrite 5/8 as 25/40 and 7/10 as 28/40. Voila! Now you have them both with the same denominator, making it easier to compare those sassy fractions.
160... I think. The series is 80+40+20+10+5+2.5+............ (Given the series is infinite it never ends but it gets pretty close to 160) = 159.99999999... ad infinitum [For future reference... series like this are basically equal to 2*the highest value e.g. 2*80=160]
