Question

What number should be added to 7/12 to get 4/15?

Answer 1

Answer:

$\frac{-19}{60}$

Step-by-step explanation:

To Find :What number should be added to $\frac{7}{12}$ to get$\frac{4}{15}$?

Solution:

Let the number be x

A number should be added to $\frac{7}{12}$ to get$\frac{4}{15}$

So, $x+\frac{7}{12}=\frac{4}{15}$

$x=\frac{4}{15}-\frac{7}{12}$

Take LCM of 15 and 12 is 60

$x=\frac{4}{15}-\frac{7}{12}$

$x=\frac{16-35}{60}$

$x=\frac{-19}{60}$

Hence $\frac{-19}{60}$ should be added to $\frac{7}{12}$ to get$\frac{4}{15}$

Answer 2

Answer:

$The\: number \frac{-19}{60}\\be\:added \:to\:\frac{7}{12}\\to\: get\:\frac{4}{15}$

Step-by-step explanation:

$Let\:the\: number \:x\\be\:added \:to\:\frac{7}{12}\\to\: get\:\frac{4}{15}$

$\implies \frac{7}{12}+x=\frac{4}{15}$

$\implies x = \frac{4}{15}-\frac{7}{12}\\=\frac{16-35}{60}\\=\frac{-19}{60}$

Therefore,

$The\: number \frac{-19}{60}\\be\:added \:to\:\frac{7}{12}\\to\: get\:\frac{4}{15}$
