Detailed explanation-1: -We can subtract two mixed numbers, by converting them to improper fractions. First, multiply the whole number by the denominator and add the numerator to get the improper fraction. Find a common denominator and adjust the numerators accordingly. Subtract the two improper fractions, and simplify the result if possible.
Detailed explanation-2: -2 1/4 + 3 1/2-2 1/3 = 4112 = 3 512 ≅ 3.4166667. Spelled result in words is forty-one twelfths (or three and five twelfths).
Detailed explanation-3: -Step 1– Convert the mixed numbers into improper fractions. Step 2– Find the common multiple of both the denominators. Step 3– Convert the fractions as common denominators. Step 4– Solve the fractions.
Detailed explanation-4: -When subtracting fractions and mixed numbers, first find a common denominator if the denominators are not alike, rewrite each fraction using the common denominator, and then subtract the numerators.
