Answer 1

Answer:

and is 30 hope it helps .................

Answer 2

Step-by-step explanation:

$\frac{2}{5} \times \frac{5}{4} - \frac{1}{6} \times \frac{3}{2} + \frac{1}{14} \times \frac{2}{5}$

$\frac{1}{2} - \frac{1}{4} + \frac{1}{35}$

lcm of 2, 4 and 35 is 140

$\frac{(1 \times 70) - (1 \times 35) + (1 \times 4)}{140}$

$\frac{70 - 35 + 4}{150}$

$\frac{39}{150}$

$\frac{13}{50}$
