Question

Find the sum of 1/7,(2/3*5/2),-5/12

Answer 1

Answer:

$\frac{39}{28}$

Step-by-step explanation:

$\frac{1}{7} +(\frac{2}{3} \times \frac{5}{2} )+\frac{-5}{12} \\=\frac{1}{7} +(\frac{5}{3}) -\frac{5}{12} \\=\frac{1 \times 12+5 \times 28 -5 \times 7}{84} \\=\frac{ 12+140 -35}{84} \\=\frac{117}{84} \\=\frac{39}{28}$
