Hello! With Grace only having 1/4 of the flour needed, that means she needs 3/4 of what the recipe calls for, because 1 - 1/4 is 3/4. For this question, we will have to multiply to see how much mroe flour Grace needs. 1 2/3 as an improper fraction is 5/3. To multiply fractions, you multiply the numbers straight across. 5/3 * 3/4 is 15/12 or 1 1/4 in simplest form. There. Grace needs 1 1/4 more cups of all purpose-flour.
