What is the answer to the equation 7/9+1/7+3/5

Step-by-step explanation:

1.52063492063

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.
