No.
To find the number you multiply by four-fifths (4/5) to get one, you need to divide one by four-fifths. This is calculated as 1 ÷ (4/5), which is equivalent to multiplying by the reciprocal of four-fifths. Therefore, you multiply by five-fourths (5/4) to get one.

no because 5 fourths is also equivalent to 5.25 and 4 fifths is also equivalent to 0.8. In addition to this, 5 fourths is also 5 pieces out of your pieces (which is greater than one) and 4 fifths is four pieces out of five pieces (which is less than one, also fifths are smaller than fourths).
no four fifths is one fifth less than five fifths
20/35? That's equivalent to 4/7.
