Question

1/4 of a number added to 1/6 of it is 15, find the number ​

Answer 1

Step-by-step explanation:

let number be x

1/ 4 of x + 1/ 6 of x = 15

6x + 4x/ 24 = 15

10 x = 24 x 15

x = 24 x 15 / 10

x = 36

Answer 2

Answer:

${\huge{\red{\underline{\underline{Question}}}}}$

$\frac{1}{4}$ of a number added to $\frac{1}{6}$ of it is 15, find the number .

${\huge{\red{\underline{\underline{Solution}}}}}$

Let the no. be x

$\frac{1}{4}of\ the\ no.$=$\frac{1}{4}of\ x$

=$\frac{1}{4}×x$

=$\frac{x}{4}$

$\frac{1}{6}of\ the\ no.$=$\frac{1}{6}of\ x$

=$\frac{1}{6}×x$

=$\frac{x}{6}$

According to given condition,

$\frac{1}{4}of\ the\ no.$+$\frac{1}{6}of\ the\ no.$=15

=>$\frac{x}{4}$+$\frac{x}{6}$=15

=>$\frac{6x+4x}{24}$=15

=>$\frac{10x}{24}$=15

=>$10x$=15×24

=>x=$\frac{360}{10}$

Hence,the no. is x=36...
