1/3
Five over six multiplied by four over seven is calculated by multiplying the numerators and the denominators. Thus, (5 × 4) / (6 × 7) = 20 / 42. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2, resulting in 10 / 21.
6 over 35
10/21 or ten over twenty-one
1 divided by 25 multiplied by z to the third power
You turn the denominator into the same value so four times three would be twelve so you multiplied the three by four so you times the one by four and then you multiplied the four by three so you would times the three by three so the answer would be 13 over twelve

0.3 or 3 over 10.
Four over seven cannot be simplified anymore than it is, sorry.

seven over twenty
1 divided by 25 multiplied by z to the third power
Four sevenths
Of those, 4/5 is the greatest.
That would be 1 over 3 multiplied by 1 over 2. So half of one-third would be one-sixth.
