Question

What should be added to 109/ 15 to get 42 /5

Answer 1

Answer:

Step-by-step explanation:

easy

let x be the required number

so now x be added to 109/15

and we get 42/5

109/15+x=42/5

109+15x/15=42/5

109+15x/3=42

x=17/15

Answer 2

17 / 15 should be added to 109/15 to get 42 / 5.

Given: The numbers 109 / 15 and 42 / 5

To Find: The number to be added to 109 / 15 to get 42 / 5

Solution: Let, the number be x.

So x should be added to 109 / 15 to get 42 / 5.

Now, the equation will be as follows:

$\frac{109}{15} + x = \frac{42}{5}$

Taking 109 / 15 to right-hand side to solve the equation:

$x = \frac{42}{5} - \frac{109}{15}$

To solve the equation we need to find the LCM of 5 and 15.

The LCM of 5 and 15 is 15.

$x = \frac{(126 - 109)}{15}$

$x = \frac{17}{15}$

Therefore, the required number is 17 / 15.
