Answer:
p = 295 / 63 = 4 43/63
Explanation:
7 1/9 = (7 x 9 + 1) / 9 = 64/9
2 3/7 = (2 x 7 + 3) / 7 = 17/7
Make the denominator of both fractions 63:
64/9 x 7/7 = 448/63
17/7 x 9/9 =153/63
So now we can rewrite the equation:
448/63 = 153/63 + p
p = 448/63 - 153/63
p = (448 - 153) / 63 = 295 / 63 = 4 43/63
