The correct answer is 1 .
Use fourths: 1/2 = 2/4, so 2/4 + 3/4 = 5/4 = 1 1/4.
Please select an answer first.
Correct answer: B
The correct answer is They let fractions use a common denominator while keeping the same values..
Equivalent fractions name the same amount with equal-size parts, which makes unlike denominators compatible.
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.
