Answer:
Step-by-step explanation:
We want to find the rational number which is equal to 
.
Let 
....eqn(1)
Multiply both sides by 10
.....eqn (2)
Subtract eqn (1) from eqn (2)
Divide both sides by 9.
Answer:
1 7/8 quarts
Step-by-step explanation:
The amount Yuan has left can be found by multiplying the original amount by the fraction he has left.
__
<h3>used</h3>
After using 1/2 of the broth for soup, the fraction remaining is ...
1 -1/2 = 1/2
The amount Yuan used for gravy is 1/4 of this, or ...
(1/4)(1/2) = 1/8 . . . of the original amount of broth
The total fraction Yuan used was ...
fraction used = fraction for soup + fraction for broth = 1/2 +1/8 = 5/8
<h3>remaining</h3>
Then the fraction remaining is ...
fraction remaining = 1 - fraction used = 1 - 5/8 = 3/8.
The amount remaining is this fraction of the original amount:
(3/8)(5 quarts) = 15/8 quarts = 1 7/8 quarts . . . . remaining
Answer:
810 boys
Step-by-step explanation:
1800 students and 55% are girls.
100%-55%=45%
1800*0.45 = 810
1800*0.55 = 990
So there are 990 girls and 810 boys.
Hope this helps :)
You would be able to make 20 subsets.
Answer:
The answer would be B, or the second option.
Step-by-step explanation:
To find the volume, you must multiply the length, width, and height of the object. (Length x Width x Height)
<em>l × w × h</em>
Replace each of the following variables with the length of each side. In this case, they are all 3, but remember that it doesn't matter in which order you put them in.
3 × 3 × 3.
Now multiply!
3 × 3 × 3 = 27 cubic feet.
Meaning, the final answer would be B.
