Question

(i)7/16- {-5/12}=?hi​

Answer 1

Answer:

answer is 41/48

Step-by-step explanation:

7/16 + 5/12

= 21 + 20 / 48

= 41 / 48

= 0.854166667

Answer 2

$\frac{7}{16} - (\frac{ - 5}{12} )$

$\longrightarrow \: lcm \: = 48$

$\frac{7 \times 3}{48} - \frac{ - 5 \times 4}{48}$

$= \frac{21}{48} - ( - \frac{20}{48} )$

$= \frac{21}{48} + \frac{20}{48}$

$\longrightarrow \: \frac{41}{48}$

Hence the answer is 41/48 ✓

More info :

Least Common Multiple(LCM) is necessary for addition and subtraction.

The smallest which makes the two multiple to be it's factor is called LCM

Now , let's find How we found LCM here

$\begin{array}{c|c}\sf 2 & \sf 16 ,12\\\ \sf 2& \sf 8,6 \ \\ \sf& \sf 4,3\\& \sf \end{array}$

Hence LCM = 2 * 2 * 4 * 3 = 48
