Are there any math genius out there? I need help with my homework.?

Question

48 is 60% of what number?
What is 175% of 48?
What percent of 90 is 50?

Answer 1

hey...are you serious?....just 48 is 60 % of 80...and the answer of your secon question is..84..and fot hte third is 55.55

Answer 2

a)
let the number beY
(60/100) Y = 48
(3/5)Y = 48
Y = 48 x 5/3 = 16 x 5 = 80
The number is 80.

b)
100% <---->48
175%<----> 175/100 x 48 = 7/ 4 x 48 = 7 x 12 = 84

c)
An examination mark of 50 out of 90 would give a % mark of 50/90 x 100 = 5/9 x 100 = 500/9 = 56% to the nearest %

Answer 3

a primer on percent

percent (%) means per 100
for example, 5% means 5 per 100 means 5/100 = 0.05

with this concept, we can ask the question
what percent is something (A) of something else (Y)?

recall percent is just the ratio of a number with 100 (that is "per 100"), so this question is asking us to compare two ratios.

x% = A/B
x/100 = A/B

notice there are three different numbers here (beside the 100):
x, A, and B.

now suppose you know only two of these, then you can ask
the question what is the third? there are three cases.

1) you know x and A. what is B?
x/100 = A/B, solve this for B we get
B = 100A/x
this can be asked this way:
A is x% of what number? this is like your first question

60% = 48/B
just solve this for B
B = 100*48/60 = 80

2) you know x and B, what is A?
x/100 = A/B, solve for A we get
A=B*x/100
or what is x% of B?
this is like your second question
what is 175% of 48
A = 48*175/100 = 84
100% of a number is that same number. more than 100% of a number is more than that number. less than 100% of a number is less than that number.
note in this case that we are asking for 175%, that is, more than 100%. our answer was 84, which as expected, is greater than 48.

3) you know A and B, what is x?
what percent of B is A? or what percent is A of B?
x/100 = A/B, solve for x
x = 100 * A/B
this is like your last question
what percent of 90 is 50?
x/100 = 50/90
x = 100 * 50/90 = 55.6
(so 50 is 55.6% of 90)

Answer 4

Q1: 48 / 60 * 100 = 80

Q2: 48 / 100 * 175 = 84

Q3: 50 / 90 *100 = 55.5555555555

Answer 5

1)
60/100 * x= 48
0.6x = 48
x = 48/.6
x = 80
2)
1% of 48 = 0.48
175% of 48= 0.48 * 175
= 84
3)
x/100 * 90= 50
90x/100 = 50
90x =50*100
x = 5000/90
x = 55.56

Answer 6

1) keep that no as x

(60 /100 ) * x =48

x = (48 * 100) / 60

th no. is 80

2)

175% of 48

= (175 / 100) * 48

= 84


3)
let x% of 90 be 50

90 * ( x / 100) = 50
x= (50 * 100) / 90

=55.55 %

Answer 7

48 is 60 percent of 80
84 is 175 percent of 48
55.5555555555555percent of 9o is 50

Answer 8

48=x 60/100

x=48*100/60
=80



48*175/100
=84



90 x/100=50
x=50*100/90
=500/9
=55,56

Answer 9

The answer is to change the form of your question:

48/X = 60/100

Factored out, X= 4800/60

Figure out the rest.

Good luck!

Answer 10

48 divided by 0.6 = 80

1.75 times 48= 84

90 divided by 50 times by 100 = 55.556

Answer 11

60% = 48
so, 100% =80

100% = 48
175% = 84

50/90 =5/9=55 5/9%
