প্রদত্ত:

6 7/15 + x = 8 3/5

ব্যবহৃত সূত্র:

x = ডানপক্ষ − বামপক্ষ 

মিশ্র ভগ্নাংশকে অপ্রকৃত ভগ্নাংশে রূপান্তর করুন

গণনা:

6 (7/15) = (6 × 15 + 7)/15 = 97/15

8 (3/5) = (8 × 5 + 3)/5 = 43/5

⇒ x = 43/5 − 97/15

5 এবং 15 এর ল.সা.গু. = 15

⇒ x = (43 × 3)/15 − 97/15

⇒ x = 129/15 − 97/15

⇒ x = (129 − 97)/15 = 32/15

⇒ x = 

∴ সঠিক উত্তর হল
