Answer:
6. If I multiply the denominator and numerator with 10 then the answer is 51/70, 54/70, 56/70 (anything between 50/70 and 60/70)
9. The answer is x+y+y+z+z+z+z
Step-by-step explanation:
6. First we have to multiply Denominator and Numerator with any number so that we may get at least 3 rational numbers between them.
We can multiply the numerator and Denominator by 4,5, 6, 7 etc.
If you don't want confusion as I have done, directly multiplied by 10.
when we multiply we get 50/70 and 60/70.
Then we have to write the rational numbers between them like-51/70, 52/70, 53/70 ,54/70 55/70 ,56/70 ,57/70 ,58/70 ,59/70.
9.We have to expand (x + 2y + 4z).
We know that 2y is y+y. And 4z is z+z+z+z.
So when we expand the answer is x+y+y+z+z+z+z.
