Sagot :

चला तर मग एकदम तपशीलवार पद्धतीने हा प्रश्न सोडवूया:

सर्वप्रथम, आपण दिलेली भिन्न संख्यांची बेरीज करण्याचा प्रयत्न करावा लागेल:
[tex]\[ \frac{4}{7} + \frac{(-11)}{7} \][/tex]

येथे, दोन्ही भिन्न संख्यांचा हाऱ्य हिस्सा हाच आहे (7). त्यामुळे आपण भिन्न संख्यांचा हाऱ्य हिस्सा राखून फक्त संख्यांशी बेरीज करु शकतो:
[tex]\[ \frac{4 + (-11)}{7} = \frac{-7}{7} = -1 \][/tex]

आता मिळालेल्या उत्तराशी (-1) आपण -7 ने गुणाकार करू.
[tex]\[ (-1) \times (-7) = 7 \][/tex]

मग, आपल्या प्रश्नाचे उत्तर 7 आहे. परिणामी, दिलेल्या उत्तरांमध्ये बरोबच होईल
