$\frac{1}{1} = 1$ $1/1=1$

$\frac{1}{2} = 0.5$ $1/2=0.5$

$\frac{1}{4} = 0.25$ $1/4=0.25$

$\frac{1}{8} = 0.125$ $1/8=0.125$

$\frac{1 \times 7}{8} = 0.125 \times 7$ $(1xx7)/8=0.125xx7$

$\frac{7}{8} = 0.875$ $color(magenta)(7/8=0.875$

Percentage is upon hundred..... so we need denominator as $100$ $100$

$100 \times 1 = 100$ $100xx1=100$

$50 \times 2 = 100$ $50xx2=100$

$33.33 \times 3 = 100$ $33.33xx3=100$

$25 \times 4 = 100$ $25xx4=100$

$20 \times 5 = 100$ $20xx5=100$

$16.66 \times 6 = 100$ $16.66xx6=100$

$14.28 \times 7 = 100$ $14.28xx7=100$

$12.5 \times 8 = 100$ $color(red)(12.5xx8=100$

Multiply both sides by 12.5

$\frac{7 \times 12.5}{8 \times 12.5} = \frac{87.5}{100}$ $(7xx12.5)/(8xx12.5)=(87.5)/100$

$\frac{7}{8} = 87.5 %$ $color(magenta)(7/8=87.5%$
