a whole number n is subtracted from the numerator of 41/55. At the same time, m is added to its denominator and the fraction now becomes 3/5 in its simplest form
given the fraction 41/77 .Find a whole number a such that when a is added to both of the numerator and the denominator of the fraction ,the resulting new fraction is equal to 4/7
A fraction is equal to 2/5 . The sum of its denominator and its numerator is 91. What is the difference between the denominator and numerator of this fraction?
Tổng của tử số và mẫu số là 91
Tỉ lệ giữa tử số và mẫu số là 2/5
Tử số là (91 : 7 ) x 2 = 26
Mẫu số là (91 : 7 ) x 5 = 65
Hiệu của mẫu số và tử số là 65 - 26 = 39
Đáp số: 39

the nummerator of a fraction is 5 less than its denominator. If both nummerator are decreased by 3, the value of the fraction becomes 6/7w what is the numerator of the original fraction.
Cho tử số của nó là \(x\)
Mẫu số của phân số đó là: \(x+5\)
Phân số đó có dạng: \(\dfrac{x}{x+5}\)
Mà giá trị của phân số này bằng \(\dfrac{6}{7}\) nên:
\(\dfrac{x}{x+5}=\dfrac{6}{7}\)
\(7\times x=6\times\left(x+5\right)\)
\(7\times x=6\times x+6\times5\)
\(7\times x-6\times x=30\)
\(x=30\)
Vậy tử số ban đầu là 30

Given fraction 79/184 . If both its denominator and its numerator are increased by M units then the new fraction will equal to 112/252 . The value of M is
Theo bài ra ta có: (79 + M)/(184 + M) = 112/252
Suy ra: 252 x (79 + M) = 112 x (184 + M)
19908 + 252 x M = 20608 + 112 x M
252 x M - 112 x M = 20608 - 19908
140 x M = 700
M = 700 : 140 = 5
Vậy: Giá trị của M là 5
Given fraction . If both its denominator and its numerator are increased by M units then the new fraction will equal to . The value of M is
Được đưa ra nếu cả hai mẫu số và tử số của nó tăng theo đơn vị M thì phần mới sẽ bằng với giá trị M .
