Multiply the whole number times the numerator. Divide the product by the denominator.

If doing it without a calculator, then convert each mixed fraction into a top-heavy equivalent fraction and then multiply as for fractions.
Because of the distributive property of multiplication over addition.
If you multiply only one of them and leave the other one alone, you have changedthe value of the fraction, and it's not the same number any more.All of these operations you're learning about ... the reason they're so technical andcomplicated is: They're all things you can do to fractions without changing the valueof the fraction. It always has to stay the samenumber.
You can reduce multiplication to repeated additions. You could also replace the resulting additions by repeated incrementing. For example, to calculate 20 + 13, continue counting 13 numbers from 20. But that would be extremely boring and inefficient. Better if you just learn to do it the way they teach in school.

You can breed (have children). That is another form of multiplying!

If you really wanted to do this, you could simulate multiplication with repeated addition.
Multiply both numbers by five- to get the fraction 85/100... which is 85%
Because of the distributive property of multiplication over addition.
To convert a mixed fraction to an improper fraction: Multiply the whole number by the denominator, and add the numerator. This will be the numerator of the result. Copy the denominator without changes to the denominator of the result.
The answer depends on the length of the string which is repeating: eg 1.142857777... or 14.142575757... and so on. As long as that is not specified, the question remains ambiguous and we cannot answer it without making guesses which cannot be justified.
The line in a fraction can be read as "divided by." Do the division. Then multiply that result by 100. 3/4 = three divided by four = 0.75 = 75%

To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator.
