Julia bought 300 pounds of grain for her horses. when a rainstorm flooded the storage shed, 30% of the grain rotted and had to be thrown out. how many pounds of grain will julia be able to use?

210

Step-by-step explanation:

10% of 300 is 30

30x3=90

30%=90

90-300=210

210 pounds

Step-by-step explanation:

So you can solve this by making an equation of 300 times 30 is equal to 100 times x so 9000 is equal to 100x so x=90.  So she can use 210 pounds.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
