G.K.K say: Multiply both numerator and denominator of 2/3 by 2. What we get is 4/6.
The denominator of 4/7 is 7 and the denominator of 4/6 is 6.
The denominator of 4/6 is less than that of 4/7.
so the fraction 4/6 is greater than 4/7
that means 2/3 is greater than 4/7
-
Amy say: 2/3 = 4/6
4/6 > 4/7
-
Abbott say: Two thirds is more than one half; four sevenths is less than one half. A number greater than one half is greater than a number less than one half.
-
Como say: 2/3 = 14/21
4/7 = 12/21
2/3 > 4/7
-
peevee say: using the common denominator 21,we get the following equivalent fractions:
2/3 = 14/21
4/7 = 12/21.
14 out of 21 is definitely greater than 12 out of 21.
Hence 2/3 is greater than 4/7.

Jim Moor say: Lots of different ways.
I love the "Butterfly Technique"
2*7 = 14
4 * 3 = 12
so 2/3 is greater!
see pic below.

Mathematically, multiply each by (1):
2/3 (7/7) = 14/21
4/7 (3/3) = 12/21
so 2/3 is greater.

MICHAEL K say: 0.667 is greater than 0.571.
-
ted s say: 14 / 21 vs 12 / 21
-
D.W. say: give the fractions a common denominator
the least common denominator is 21
2/3 = 14/21
4/7 = 12/21
14>12, so 2/3 > 4/7
-
Aima Wiiner say: Because the numbers are smaller of course
-
BEER GLASS CELL PHONE response say: first you make the denominator the same that is divisable by both 3 and 7 and that is 21(so 3x7=21 so the top number has to be increased by x7 so that is 14/21 -- 7x3= 21 (so the top number is increased by 3 so 4x3=12 or 12/21--------------14/21 vs 12/21 and that is the way all fractions are done.

Amie say: Oh god maths
-
kd say: Check in calculator
-
Paul say: To compare fractions just make the denominators the same.
