The correct question is
<span>A student ate 3/20 of all candies and another 1.2 lb. Another student ate 3/5 of the candies and the remaining 0.3 lb. Altogether, what weight of candies did they eat?</span>
let
x-------> total <span>weight of candies
we know that
x=(3/20)*x+1.2+(3/5)*x+0.3
</span>x=(3/20)*x+(3/5)*x+1.5----> multiply by 20----> 20x=3x+12x+30
20x=15x+30
20x-15x=30
5x=30
x=6 lb
the answer is
6 lb
125/27 , or 4 & 25/27 , or 4.62963

Answer:
She would run about 5.8 miles in 64 min.
Step-by-step explanation:
Let m= miles per minute
7=80m divide 80 on both sides.
0.0875=m Round
0.09 miles per minute
0.09 x 64= 5.76 round or leave it like that
5.8
We want to find out how many times 16 goes into 40.
It goes into 40 twice, with 4 leftover.
2 4/16
Now we can simplify.
Divide the numerator & denominator by 4:
1/4
Our final answer is 2 1/4.
