Answer 1

0.86 is the answer for your question dear

Answer 2

Answer:

$\displaystyle \: \frac{1}{12} + \frac{7}{9}$

• Multiples of 12={12,24,36,48,60}
• Multiples of 9={9,18,27,36,45,54}
• The least common multiple=36

So,

$\displaystyle{ \frac{1}{12} = \frac{1 \times 3}{12 \times 3} = \frac{3}{36} }$

$\displaystyle{ \frac{7}{9} = \frac{7 \times 4}{9 \times 4} = \frac{28}{36} }$

Now,

$\displaystyle{ \frac{3}{36} + \frac{28}{36} = \frac{3 + 28}{36} = \frac{31}{36} }$
