A recipe needs teaspoon black pepper and red pepper. ________ more black pepper is needed than red pepper for this recipe.

Hint:

In this we question we have given recipes and we need to calculate how more black pepper is needed than red pepper. So, have to subtract the fraction to get the total length of the pool. This can be done by fraction adding and for that we have to make denominator same this can be done by taking LCM. LCM is the least common multiple of two integers. We will use the prime factorization method to find the LCM. In prime factorization method the simply put the factor of each number and then for LCM we take product of factors by considering the repeated factors only one time with highest exponent.
