Order these from least to greatest 3 39/40 , 3 19/20 , 3 1/2

Lera25 [3.4K]

Hey!

First change all the fractions so that they have a common denominator: 40

$3 \frac{39}{40} = 3 \frac{39}{40}$

$3 \frac{19 \times 2}{20 \times 2} = 3 \frac{38}{40}$

$3 \frac{1 \times 20}{2 \times 20} = 3 \frac{20}{40}$

Now order them:

$3 \frac{39}{40} , 3 \frac{19}{20} , 3 \frac{1}{2}$

Good luck and hope this helps! :)

The classroom outside bag had 5 frisbees in it. If 25% of the outside toys are frisbees, then how many total toys are in the bag

malfutka [58]

So 25%=1/4 so technically you just do 5 times 4 since you need 4 more to have a full 4/4 or full 100% so 5 times 4 is 20 so there are 20 totals toys in the bag
