20/64=5/17
4/5 x 5/8 is 1/2.
5/8 x 4/15 is 1/6.
46/8 = 5 and 3/4
4 and 5 eighths = 4 + 5 eighths of 4 + (5/8) = 4 + 0.625 = 4.625
30 * 5/8 = 75/4
1/4 x 5/8 = 5/32
5/8 x 2/5 = 10/40 = 1/4
It is: 1 and 5/8 times 10 = 16 and 1/4
5/8 x 3/4 is 15/32
4/8 x 9/8 is 9/16.
To express five eighths in fortieths, start by converting five eighths into a fraction with a denominator of 40. Since 8 times 5 equals 40, multiply both the numerator and the denominator of five eighths (5/8) by 5: [ \frac{5 \times 5}{8 \times 5} = \frac{25}{40}. ] Thus, five eighths is equivalent to twenty-five fortieths.
five eighths 5/4 x 1/2 = (5x1) / (4x2) = 5/8
