Question 345600
1. .75=3/4  so .8=80/100 or 8/10 or {{{highlight(4/5)}}}
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(1/5)}}}
3. 50/2=25 so 3.2*25= {{{highlight(80)}}}
4. 14 is 1/2 of 28 so 5 is 1/2 of {{{highlight(10)}}}
5. 1 is multiplied by 1/4 so when 5/25 is multiplied by 1/4 we get 5/100 or {{{highlight(1/20)}}}
6. .35*20=7 so .45*20={{{highlight(9)}}}
7. 2/18=(1/9)(2/2) and (1/3)*(1/3)=1/9 so (1/12)*(1/3)=(1/36)(2/2)= {{{highlight(2/72)}}}
8. 3/8 * 4/4 =12/32 so 2/5 * 4/4 = {{{highlight(8/20)}}}
9. hmm im taking guess on this one: (1/3)*(1/2)=(1/6) so (3/7)*(1/2)= {{{highlight(3/14)}}} 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(3/5)}}}
12. .2*2=.4 so .3*2={{{highlight(.6)}}}
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(13/20)}}}
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(8/5)}}}
17. .30x=.075 so x=.25 then .15x=y where {{{.15(.25)=highlight(.0375)}}}
18. basically 40%is to 20% (its half) as 75% is to 37.5%
19. {{{625=5^4}}} {{{81=3^4}}} 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
