Expressed as a top-heavy fraction, 4/5-1 = 5/4
5.45
five ninths
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.
To find out how many four-fifths are in 8, you can divide 8 by four-fifths. This is done by multiplying 8 by the reciprocal of four-fifths, which is five-fourths. Therefore, ( 8 \div \frac{4}{5} = 8 \times \frac{5}{4} = 10 ). So, there are 10 four-fifths in 8.
11¼. Division by a fraction is mathematically equivalent to multiplication by its reciprocal.9 divided by four fifths in simplest form is 45 over 4
To divide four fifths by four fifteenths, you can multiply four fifths by the reciprocal of four fifteenths. This means you calculate ( \frac{4}{5} \div \frac{4}{15} = \frac{4}{5} \times \frac{15}{4} ). The fours cancel out, resulting in ( \frac{15}{5} ), which simplifies to 3. Thus, four fifths divided by four fifteenths equals 3.
