Tomas can compare 3/8 to 3/4 without using fraction strips.

He says that a whole divided into 8 equal parts will have larger parts than the same whole divided into 4 equal parts.

Three larger parts must be greater than 3 smaller parts, so 3/8 is greater than 3/4 .

Is Tom correct?

• Yes, 8 is greater than 4 so 3/8 is greater than 3/4

• No, the fractions are equal

• No, 1 of 8 equal parts is less than 1 of 4 equal parts of the same whole

• No, you cannot compare fractions with different denominators

Her sister Libby hiked 3/6 of the same trail.

• Libby

Which is a true comparison?

Sally and Ethan have the same science homework.

Sally finished 2/3 of the homework.

Ethan finished 4/6 of the homework.

Conjecture: Sally and Ethan finished the same amount of homework.

Is the conjecture true?

• Yes, 2/3 and 4/6 name the same point on the number line, so the fractions are equivalent.

• Yes, 2/3 and 4/6 name the same points on the number line, so the fractions are not equivalent.

• No, 2/3 and 4/6 name the same points on the number line, so the fractions are equivalent.

• No, 2/3 and 4/6 different points on the number line, so the fractions are not equivalent.

For the pair of fractions, write the equivalent whole number.

8/8 = 3/3

For the pair of fractions, write the equivalent whole number.

8/2 = 12/3

For the pair of fractions, write the equivalent whole number.

12/6 = 6/3
