To clear fractions in the equation \( 13x + 16y = 4 \), we first check if there are any fractions in the equation. Since all the coefficients and the constant term are integers, the equation does not contain any fractions that need to be eliminated.
Therefore, Rashonda does not need to multiply the equation by any number to clear fractions, as there are none present.
If there were fractions, she would typically multiply the entire equation by the denominator of the fractions involved to eliminate them, but in this case, no such action is necessary.
