Answer:
3/10
Step-by-step explanation:
1. find the lowest common denominator which is 10.
2. for 4/5 you have to multiply 5 by 2 in order to get 10, so you multiply the numerator by 2 as well which gives you 8/10.
3. for 1/2 you have to multiply 2 by 5 in order to get 10, so you multiply the numerator by 5 also which gives you 5/10
4. you work out the difference between both numerators which is 3 and keep the denominator the same

Water freezes at 32 °F.
2.06×10^14
nth term of G.p = ar^n-1
the first term, a = 3 common ratio, r = 2nd term/ 1st term, 3rd term/ 2nd term, etc.
r = 9/3 = 3
30th term = 3(3)^30-1 = 2.06×10^14
Look at the one I wrote underneath. The answer is B
