Question

(7/8×8/7)+(-5/9)×(6/-25)
​

Answer 1

Answer:

$\frac{17}{15}$

Step-by-step explanation:

To do this sum we have a use a rule of simplification.

So, What's the rule? ^_*

The name of the rule is "BODMAS"

Now, a question should arise in your mind that what's BODMAS.

HERE IS THE ANSWER !

B=Brackets.

O=Off.

D=Division.

M=Multiplication.

A=Addition.

S=Subtraction.

These letters are written in this order because..

There are some hierarchy in these words ....

That means B is simplified first then O then D and so on...

B > O > D >M > A > S

Applying this rule in your question : -

$(\frac{7}{8} \times \frac{8}{7} ) + ( - \frac{5}{9} ) \times ( - \frac{6}{25} ) \\ \\ = 1 + ( \frac{ - 30}{ - 225} ) \\ \\ = 1 + \frac{2}{15} \\ \\ = \frac{17}{15}$
