Four fifths of a number is less than three fourth of the number by 4
Answers
Answer:
Let the number = x, then
4x/5 =(15x/4) + 4
16x = 75x + 80
-59x = 80, or
x = -80/59. Answer.
The answer seems absurd because the question is also absurd.
Check: (4/5)*(-80/59) = -1.084745763
RHS = 4+(15/4)*(-80/59) = -1.084745763
Four-fifths of a number is greater than three-fourths of a number by 8. What is the number?
The sum of two numbers is 34. Four times the lesser number is four less than the greater number. What are the numbers?
Two less than four-fifths of a number is seven, what is the number?
Two less than four fifths of a number is 18. What is the number?
One third of three fifths of one fourth of a number is 30. What is 80% of that number?
Let the number be X
According to Question,
4X/5 = 3X/4 + 4
4X/5 - 3X/4 = 4
(16X-15X)/20 = 4
X = 4×20 = 80 (Ans.)
Second Method,
4/5 = 80%
3/4 = 75%
80% - 75% = 5%
5% = 4
THEN,
100% = 4×20 = 80 (Ans.)
Flexible support where it's needed.
Let the number is n. Now 4n/5=3n/4+4, or 4n/5-3n/4=4, or (16n-15n)/20=4, or n=80. The number is 8.
Let the number be x, As per statenent
4/5×x-3/4×x=4
4x/5–3x/4=4
16x-15x=4×20
x=80
Means the number is 80
Now check the answer
4/5×80–3/4×80=4
64–60=4
4=4
Means answer is correct
Answer the number is 80
What is the number whose one-fifth is less than the one-fourth by 3?
Four fifth of a number is more than three fourth of the number by 4. What is the number?
Two-thirds of three-fourths of one-fifth of a number is 15. What is 30 percent of that number?
If three quarters of a number is 15, who can work out four fifths of the number?
Twice a number is 24 greater than its half. What is the number?
45x−34x=4
16–1520x=4
120x=4
x=80
Alternative,
let the number be 20
four-fifth=16
three-fourth=15
16–15=1
When the difference is 1, the number is 20
if the difference is 4, the number must be 4*20=80
Let the no. be x
Four-fifth of x=(4/5)*x=4x/5
three-fourth of x=(3/4)*x=3x/4
According to question
(4x/5)-(3x/4)=4
(16x-15x) /20=4
x=4*20
x=80
Hence the required no is 80

Suppose that the number is A.
Then,we have
4A/5=(3A/4) + 4
On Multiplying both sides by LCM of denominators i.e.20,we get
16A=15A+80
16A-15A=80
A=80(Answer).
Let the number be x
From the question,
4x/5-3 3x/4=4
4x/5–15x/4=4
-59x/20=4
-59x=80
x=-1.3559
Let the number be x.
x×(4/5) - x ×(3/4) =x×( 4×4–3×5)/20
=x×(16–15)/20 =x/20 =4
x=4×20=80
Let the number be X, so as per the given information it is as follows…
(4/5*X)-(3/4*X)=4
By solving for X, we get the number as 80
Let the required number is x
then (4/5)x -(3/4)x = 4
(16/20) x - (15/20) x = 4 (LCM of 4 and 5 is 20)
(1/20) x = 4
x = 4×20 = 80
4/5*x-3/4*x = 4
suppose the number = x
then 4/5*x-3/4*x =4
16 x-15 x/20 =4
16 x-15 x =4*20
x =80
the number =80
4x/5 = 3x/4+4
(16x - 15x)/20 = 4
x= 4*20 =80
number is 80
4x/5 - 3x/4 = 4
(16–15) x = 20×4
x = 80
80.
Suppose the number is x then
4x/5=3x/4+4
16x=15x+80
so x=80
(4/5)X=(3/4)X+4
4x/5=3x+16)/4
16x=15x+80
X=80
