She has solved two sevenths of them

Problems Solved = “two sevenths of them”

Replace the words “two sevenths” with the fraction “2/7”

Problems Solved = “2/7 of them”

Replace the word “them” with the number “21”

Problems Solved = “2/7 of 21”

Replace the word “of” with a multiplication sign.

Problems Solved = (2/7) * 21

Compute the final answer by multiplying the numbers

Problems Solved = (2/7) * 21

Problems Solved = (2) * (21/7)

Problems Solved = (2) * (3)

Problems Solved = 6

>>> The final answer is: 6 problems
