479/315
Step-by-step explanation:
1.) Add: 7 / 9 + 1 / 7 = 7 · 7 / 9 · 7 + 1 · 9 / 7 · 9 = 49 / 63 + 9 / 63 = 49 + 9 / 63 = 58 / 63
The common denominator you can calculate as the least common multiple of the both denominators - LCM (9, 7) = 63. The fraction result cannot be further simplified by cancelling.
In words - seven ninths plus one seventh = fifty-eight sixty-thirds.
2.) Add: the result of step
No. 1 + 3 / 5 = 58 / 63 + 3 / 5 = 58 · 5 / 63 · 5 + 3·63 / 5·63 = 290 / 315 + 189 / 315
= 290 + 189 / 315 = 479 / 315
The common denominator you can calculate as the least common multiple of the both denominators - LCM (63, 5) = 315. The fraction result cannot be further simplified by cancelling.
In words - fifty-eight sixty-thirds plus three fifths = four hundred seventy-nine three-hundred fifteenths.
