Question

1. Find the sum of the following :
( i ) 9/13 and 6/13

2. Simplify :
( i ) 7/-12 + (5/-13)

3. Divide :
( i ) 2 by ¼

​

Answer 1

Answer:

the answer of first is 15 /3

Answer 2

Step-by-step explanation:

1. $\frac{9}{13}$ + $\frac{6}{13}$ = $\frac{15}{13}$

✤ Hence, Denominators are same add directly numerators

• $\frac{9~+~6}{13}$

• $\frac{15}{13}$ ✅

2. $\frac{7}{-12}$ + $\frac{5}{-13}$ = $\frac{-151}{156}$

• $\frac{-7}{12}$ + ($\frac{-5}{13}$)

• - $\frac{7}{12}$ - $\frac{5}{13}$

✤ LCM of 12 and 13 is 156

• $\frac{ - \: 91 \: - 60}{156}$

• $\frac{-151}{156}$ ✅

3. $\frac{ 2 }{ \frac{1}{4} }$ = 8

• 2 × $\frac{4}{1}$

• 8 ✅
