Fractions equal to 3/10
Multiply the top and bottom by the same number and the amount doesn't change: 3 × 2 = 6 and 10 × 2 = 20, so 3/10 = 6/20. Times 3 gives 9/30. In the bakery, that's the same pie with every slice cut in two, then in three.
More fractions equal to 3/10: 6/20, 9/30, 12/40, 15/50, 18/60. The equivalent fractions lesson shows why this always works.
Is 3/10 bigger than one half?
3/10 is smaller than 1/2. One half of 10 parts is 5, and 3/10 has 3, which is fewer. Next to its neighbors: 2/10 < 3/10 < 4/10.
3/10 in real life
Share the 20 into 10 equal groups: 20 ÷ 10 = 2 in each group. Take 3 groups: 2 × 3 = 6.
An hour has 60 minutes. 60 ÷ 10 = 6, and 6 × 3 = 18 minutes.
Cut into fifths, then halve each fifth. This is why tenths and fifths are such close friends.
Common mix-ups with 3/10
Swapping the numbers changes everything. 3/10 is less than one whole; 10/3 is more than one whole. The bottom number always says how many equal parts make up the whole.
A pie with 3 filled and 7 empty is not 3/7. That compares the filled part to the empty part. The bottom number counts all 10 parts, filled or not.
