Question

3 upon 7 plus -4 upon 9​

Answer 1

Answer:

3/7+-4/9.................

Answer 2

Answer:

$\frac{-1}{63}$ is the required value of  $\frac{3}{7}$ + $(\frac{-4}{9} )$

Step-by-step explanation:

Explanation:

Given that, $\frac{3}{7}$ + $(\frac{-4}{9} )$

For this question first, we find out the LCM of  7 and 9.

• And we know that LCM the smallest positive integer that is divisible by both a and b is known as the least common multiple (lcm), lowest common multiple, or smallest common multiple of two numbers a and b in mathematics and number theory.

• For example,  8 and 4 are the two numbers. The factor of 8 is 2×2×2 and the factor of 4 is 2×2.

• So, the LCM of 4 and 8 is 2 ×2 × 2 = 8

Step 1:

We have,  $\frac{3}{7}$ + $(\frac{-4}{9} )$

Factor of 7 = 1 ×7

Factor of 9 = 1 × 3 × 3

LCM of  7 and 9  = 7 × 3 × 3 = 63

⇒$\frac{27 - 28}{63}$ = $\frac{-1}{63}$

Final answer:

Hence, $\frac{-1}{63}$ is the required value of  $\frac{3}{7}$ + $(\frac{-4}{9} )$.
