This is the concept of algebra, given that the area of a rectangular pool is (15x-9), the possible dimensions of the pool by factoring will be:
Area=length×width
Area=(15x-9)
factoring the above we get:
Area=3(5x-3)
therefore the possible dimension will be:
length=5x units
width=3 units
1) 20*3/5, use the rule a*b/c=ab/c

D is your answer
2) 1/5*8 =1.6, and 1.6 as a fraction is 
Just gonna show real quick how I converted this decimal into a fraction...
- Split the number into its whole number component and decimal component, 1.6=1+0.6. .6=6/10, and 1 is a whole number, and 6/10 reduced is 3/5. So your answer is
.
3) Two thirds of 93 is 62, and you can word this as 2/3*93=62.
4) Three-fifths of 30 is 18, like the other problem, 3/5*30=18.
5) She has one liter cotainers and each of them are 2/3rds full. So to find how much sports drink is in 5 of the containers, you have to do 5*2/3=
. You multiply 2/3 times 5 because each container has 2/3rds, and there are five containers.
Hope this helps, have a BLESSED and wonderful day, as well as a safe one!
