Grade 3 equivalent fractions answers: exercises 1 to 10
Exercise 1 – Halves and fourths
The shaded part of the fourths bar is 2 parts of 4. It matches the halves bar.
Answer: \(\frac{2}{4}\)
Exercise 2 – Thirds and sixths
Each third is cut into 2 sixths, so one third is 2 sixths.
Answer: \(\frac{2}{6}\)
Exercise 3 – Sixths and halves on lines
The dashed line passes through the middle mark of the halves line.
Answer: \(\frac{1}{2}\)
Exercise 4 – Fill the blank
Each fourth is 2 eighths, so 3 fourths are 6 eighths.
Answer: \(\frac{6}{8}\)
Exercise 5 – Equal to one half
Half of 4 parts is 2, half of 6 is 3, and half of 8 is 4.
Answer: \(\frac{2}{4}\), \(\frac{3}{6}\), \(\frac{4}{8}\)
Exercise 6 – Missing numerators
- \(\frac{1}{4} = \frac{2}{8}\)
- \(\frac{4}{8} = \frac{1}{2}\)
- \(\frac{4}{6} = \frac{2}{3}\)
Exercise 7 – Fractions equal to a whole
- 1
- 2
- 5
Exercise 8 – Whole number on the line
P is 4 halves from 0.
Answer: \(\frac{4}{2}\) = 2
Exercise 9 – Whole numbers as fractions
- \(\frac{3}{1}\)
- \(\frac{8}{4}\)
- \(\frac{6}{6}\)
Exercise 10 – Same denominator
- \(\frac{3}{8} < \frac{5}{8}\)
- \(\frac{6}{6} > \frac{4}{6}\)
- \(\frac{1}{3} < \frac{2}{3}\)
Exercises 11 and up
Exercise 11 – Same numerator with bars
The fourths bar has more shaded length.
Answer: \(\frac{3}{4} > \frac{3}{8}\)
Exercise 12 – Same numerator
- \(\frac{2}{3} > \frac{2}{6}\)
- \(\frac{5}{8} < \frac{5}{6}\)
- \(\frac{1}{2} > \frac{1}{4}\)
Exercise 13 – Which point is greater
B is farther right than A.
Answer: B; \(\frac{4}{6} > \frac{1}{6}\)
Exercise 14 – Order the fractions
All numerators are 1, so bigger denominators mean smaller parts.
Answer: \(\frac{1}{8}\), \(\frac{1}{6}\), \(\frac{1}{3}\), \(\frac{1}{2}\)
Exercise 15 – Banana loaves
Maya ate \(\frac{6}{8}\) and Sofia ate \(\frac{3}{4}\). Both shaded lengths are equal, so the fractions are equivalent.
Answer: Yes, \(\frac{6}{8}\) = \(\frac{3}{4}\)
Exercise 16 – Who ran farther
The numerators match. Fourths are bigger than eighths.
Answer: Liam; \(\frac{3}{4} > \frac{3}{8}\)
Exercise 17 – Painted boards
- Jamal, because 5 sixths is greater than 3 sixths.
- 5 – 3 = 2, so \(\frac{2}{6}\) more.
Exercise 18 – Noah's rule
The denominator tells how many equal parts the whole has. More parts means each part is smaller, so fourths are smaller than thirds.
Answer: \(\frac{1}{4} < \frac{1}{3}\)
Exercise 19 – Scoops of rice
Priya: 9 thirds, and every 3 thirds make 1 cup, so \(\frac{9}{3}\) = 3 cups. Diego: 12 fourths, and every 4 fourths make 1 cup, so \(\frac{12}{4}\) = 3 cups.
Answer: Neither. Both poured 3 cups.
Exercise 20 – Ribbon contest
- Diego, because \(\frac{3}{6}\) = \(\frac{1}{2}\).
- \(\frac{2}{3} = \frac{4}{6}\), so the order is \(\frac{3}{6}\), \(\frac{2}{3}\), \(\frac{5}{6}\) (Diego, Priya, Mei).
Key facts behind this grade 3 equivalent fractions answers
- Equivalent fractions name the same amount and sit at the same point on a number line.
- Examples with denominators 2, 3, 4, 6, and 8: 1/2 = 2/4 = 4/8 and 2/3 = 4/6.
- A fraction with the same top and bottom number equals 1, and n/1 equals n.
- Same denominator: the greater numerator makes the greater fraction.
- Same numerator: the smaller denominator makes the greater fraction.
