Correct answer: A
The correct answer is 4 .
Rewrite 1/3 as 2/6: 1 5/6 + 2 2/6 = 3 7/6 = 4 1/6.
Please select an answer first.
Correct answer: B
The correct answer is Regroup one whole as an equivalent fraction before subtracting..
Regrouping one whole creates enough fractional parts to subtract accurately.
No. Use a common denominator, then add or subtract the numerators while keeping the denominator.
Equivalent fractions keep the same value while expressing the parts with a common denominator, which makes unlike fractions easier to combine.
