✔ 最佳答案
So the question is 4.25%x=8.54.25%=.0425
So we get
.0425x=8.5
x=8.5/.0425
x=200
So the unknown is 200.

= 8.5/(4 1/4%)
= (8 1/2)/([4 1/4]/100)
= (17/2)/([17/4]/100)
= (17/2)/(17/400)
= 17/2(400/17)
= ([17/17]/[2/2])([400/2]/[17/17])
= 200
Answer: 200
= (8 1/2)/([4 1/4]/100)
= (17/2)/([17/4]/100)
= (17/2)/(17/400)
= 17/2(400/17)
= ([17/17]/[2/2])([400/2]/[17/17])
= 200

8.5 ÷ (4 1/4)%
= 8.5 ÷ (16/4 + 1/4)/100
= 8.5 x 100/(17/4)
= 850/(17/4)
= 850(4/17)
= 200
= 8.5 ÷ (16/4 + 1/4)/100
= 8.5 x 100/(17/4)
= 850/(17/4)
= 850(4/17)
= 200

4 1/4 equals tp 17/4 %
every time u see % it means it divide with 100
17/4 / 100 x X = 8.5
17X/400 = 8.5
17X = 3400
X =200

[4 1/4] /100 x ?=8.5
?=8.5 /(4 1/4/100)=8.5/0.0425=200
=================================================
Double check; 4 1/4 /100 x200=4 1/4 x 2=8.5
good luck.

Let's call the number we are trying to find x.
4 1/4% * x = 8.5
4 1/4 = 4.25%
Convert the % into a fraction
4.25/100 * x = 8.5
Multiply both sides by 100/4.25 to get x on its own
x = 100/4.25 * 8.5
x = 850/4.25 = 85000/425 = 200
4 1/4% * x = 8.5
4 1/4 = 4.25%
Convert the % into a fraction
4.25/100 * x = 8.5
Multiply both sides by 100/4.25 to get x on its own
x = 100/4.25 * 8.5
x = 850/4.25 = 85000/425 = 200

well 41/4% of something can be expressed in decimals as 0.0425. so you have a problem where n represents your mystery number and you times it by 0.0425. So 0.0425 x n = 8.5
To figure out what n (your mystery number) equal just divide 8.5 by 0.0425 and that'll give you *drum roll* n or ? equal 200

4 1/4 % of (?) = 8.5 OR (?) = 8 1/2 divided by 4 1/4 % = 2 /% = 200

just convert 4 1/4% to decimal, which is 0.0425, then divide 8.5 by that value, 0.0425, then you'll get the number..
