if you don't know you could just multiply top and bottom by 2*7*9 (which is actually the lcm in this case of 2 and 7 and 9)

Answer 8

126?

Answer 9

\[\frac{2 \cdot 7 \cdot 9 \cdot \frac{1}{2}}{2 \cdot 7 \cdot 9 \cdot \frac{3}{7}+2 \cdot 7 \cdot 9 \cdot \frac{1}{9}}\]

Answer 10

\[\frac{ 7 \cdot 9 \cdot 1 }{2 \cdot 9 \cdot 3+2 \cdot 7 \cdot 1}\]

Answer 13

the top is 63
the bottom is 54+14 which is 68

Answer 14

ok thank you

Answer 15

so you ever have trouble thinking of the lcm
you could just multiply the bottoms together of the mini-fractions
this may be a multiple of the lcm but it will work you just might have to reduce some in the end

Answer 16

reduce some more in the end*
