16*87.5 = 1400
Half of 174 is 87
87 and a half percent:87 1/2%= 87.5%= 0.875 in decimal= 875/1000 or 7/8 in fraction
175/2
87.5
1/3rd of 87 = 87*1/3 = 29
Yes, one half divided by one half is one fourth.
0.875
around three and a half
Half of 174 is 87
The half-life of Rubidium-87 is about 48.8 billion years. To determine the number of half-lives in 4.6 billion years, you divide the age of the Earth by the half-life of Rubidium-87: 4.6 billion years / 48.8 billion years ≈ 0.0943 half-lives. Thus, the age of the Earth represents approximately 0.09 half-lives of Rubidium-87.
87.5% = 0.875.875 x 48 = 42
87 and a half percent:87 1/2%= 87.5%= 0.875 in decimal= 875/1000 or 7/8 in fraction
The half-life of Rb-87 is approximately 48.8 billion years. This means that it takes that amount of time for half of a sample of Rb-87 to decay into its daughter isotopes.
175/2
87.5
87
the answer is 43.5.
