Question

7/3 x 2/5 + 1/6 x (3 )/9 - 2/5 x 1/9

Answer 1

Answer:

$17/18$

Step-by-step explanation:

$7/3 \times 2/5 + 1/6 \times 3/9 - 2/5 \times 1/9$

$14/15+3/54-2/45$

$89/90-2/45$

$=17/18$

Answer 2

Answer:

Step-by-step explanation:

$\frac{7}{3}*\frac{2}{5}+\frac{1}{6}*\frac{3}{9}-\frac{2}{5}*\frac{1}{9}\\\\=\frac{14}{15}+\frac{1}{18}-\frac{2}{45}$

LCD = 90

$=\frac{14*6}{15*6}+\frac{1*5}{18*5}-\frac{2*2}{45*2}\\\\=\frac{84}{90}+\frac{5}{90}-\frac{4}{90}\\\\=\frac{84+5-4}{90}\\\\=\frac{85}{90}\\\\=\frac{17}{18}$
