In the given problem of proportion , 75 is the number whose 5 4 ​ th part is 60.
A **proportion **is a statement that two ratios or fractions are equivalent. It expresses the equality between two ratios or **fractions **by using the **symbol **"=", indicating that the two fractions represent the same value.
A proportion consists of four parts: two ratios or fractions , each having a **numerator **and a denominator. It is typically written in the form of:
b a ​ = d c ​ .
Here, "a" and "b" are the **numerators **of the first ratio, while "c" and "d" are the numerators and denominators of the second ratio , respectively.
Let x be the **number **whose 5 4 ​ part is 60.
Then,
x × 5 4 ​ = 60
Multiply 4 5 ​ both sides,
x × 5 4 ​ × 4 5 ​ = 60 × 4 5 ​ ,
x = 15 × 5,
x = 75.
So, 60 is 5 4 ​ th **part **of 75.
