Alekssandra [29.7K]
Hello! To find the amount of lettuce needed for the recipe, all you have to do is multiply 1 3/4 by 4 1/7. It would be best to change the numbers into improper fractions. 1 3/4 is 7/4 and 4 1/7 is 29/7. 7/4 * 29/7 is 203/28 or 7 1/4 in simplest form. You need 7 1/4 cups of lettuce for the salad recipe.
