Please help me answer these number series. I also need the solutions on how the answers are being solved. I definitely need this for my homework. Thank you so much for all that you do for us students who are having difficulty in Math.

You can put this solution on YOUR website!
1. .75=3/4 so .8=80/100 or 8/10 or highlight%284%2F5%29
2. 1/2=50% so 75% is 25% more than 1/2, so if 45%is 25% more than X then X=20% in a fraction form. 20%=.2=20/100=2/10=highlight%281%2F5%29
3. 50/2=25 so 3.2*25= highlight%2880%29
4. 14 is 1/2 of 28 so 5 is 1/2 of highlight%2810%29
5. 1 is multiplied by 1/4 so when 5/25 is multiplied by 1/4 we get 5/100 or highlight%281%2F20%29
6. .35*20=7 so .45*20=highlight%289%29
7. 2/18=(1/9)(2/2) and (1/3)*(1/3)=1/9 so (1/12)*(1/3)=(1/36)(2/2)= highlight%282%2F72%29
8. 3/8 * 4/4 =12/32 so 2/5 * 4/4 = highlight%288%2F20%29
9. hmm im taking guess on this one: (1/3)*(1/2)=(1/6) so (3/7)*(1/2)= highlight%283%2F14%29 just a guess tho
10. this is the same question as #9
11. 0.4=2/5 (2/5=40/100) so .6 =60/100=6/10= highlight%283%2F5%29
12. .2*2=.4 so .3*2=highlight%28.6%29
13. Guessing? 23/8=2.875 so x/27=2.875 => 77.625,,,,or,,,,8*3=24-1=23 and 27*3=81-1=80
14. .5=1/2 so .65=65/100=highlight%2813%2F20%29
15. wow im too tired id say 4 because 2/8=1/4 and 1/3to 3 is like 1/4 to 4
16. basically 30% is to 60% as 80% is to160% so 160/100=16/10=highlight%288%2F5%29
17. .30x=.075 so x=.25 then .15x=y where .15%28.25%29=highlight%28.0375%29
18. basically 40%is to 20% (its half) as 75% is to 37.5%
19. 625=5%5E4 81=3%5E4 so 5 is to 3 not positive but it looks right
20. ?
21. 4.5,added a .5
22. 16, 2*4=8 4*4=16


Good luck im tired good night
