Which is biggest?

Question

a1/5 or 2/10
b 3/7 or 6/21
c 10/15 or 4/6
d 1/3 or 33/100

Answer 1

You can just convert them all to decimals to find out.

a) .2
b) .428
c) .66
d) .33

So, clearly, c is the largest.

Answer 2

a1/5 or 2/10 they are equal
b 3/7 or 6/21 3/7 = 9/21 therefore 3/7> 6/21
c 10/15 or 4/6 10/15 = 20/30 and 4/6 = 20/30
therefore, they are equal

d 1/3 or 33/100 1/3 = 33/99 therefore 1/3 > 33/100
(because 99<100)

Answer 3

a) 1/5=2/10

b) 3/7=9/21 is greater than 6/21

c) 10/15 = 4/6 =2/3

d) 1/3= 33/99 is greater than 99/100

Answer 4

a 1/5 compared to 3/7, 3/7 is bigger
b 3/7 compared to 10/15, 10/15 is bigger
c 10/15 compared to 1/3, 10/15 is bigger

There for 10/15 or 2/3 is the biggest.

Answer 5

a] 2/10=(1*2)/(5*2)=1/5 .. so 1/5=2/10
b] 6/21=(2*3)/(7*3)=2/7 .. so 3/7>2/7
c] 10/15=(2*5)/(3*5)=2/3 and 4/6=(2*2)/(2*3)=2/3 .. so 10/15=4/6
d] 1/3=33/(3*33)=33/99 .. so we have to divide both numbers by 33 and we obtain 1/99 and 1/100 ... so 1/99>1/100

or...
a] =
b] >
c] =
d] >

Answer 6

a. equal >>>multiply 1/5 by 2/2

b. 3/7 >>>multiply 3/7 by 3/3 then 3/7 = 9/21 > 6/21

c. equal >>>divide 10/15 by 5/5 = 2/3 ; divide 4/6 by 2/2 = 2/3

d. 1/3

Answer 7

Answer C.

10/15 to 4/6 to 2/3

Then goes: 3/7,1/3, and 1/5.

The way to figure the largest fraction is taking the top number divided by the bottom number and comparing them to the other fractions.
