Answer 2

Given,

Ram did two parts of a cake in the ratio $3:7$

Let, the ratio of two parts be $3x,7x$

The total cake $= 100$%

The total cake $=3x+7x$

$3x+7x=100$%

$10x=100$%

$x= \frac{100}{10}$

$x=10$%

Substitute $x=10$% in $3x$ and $7x$

$3x=3\times10$

$= 30$%

$7x=7\times10$

$= 70$%

Therefore, the percentages of each part is $30$% and $70$%.
