Answer:
1/5 = 0.2, 25% = 0.25, 4 out of 20 = 0.2
Answer:
3.5
Step-by-step explanation:
If the shape is half of a circle, you will be using this formula: A = π
Your radius is half of the diameter. r = d/2 = 3/2 = 1.5
Substitute r = 1.5 into the formula.
A = π
A = (3.14)
Use your calculator to find the answer and round your answer.
3.5
So this question is just a comparison problem.
If you split a chocolate bar into seven pieces, and ate 5 of them, you would have eaten less than if it were split into 10 pieces and you ate 8.
Another way to see this is if we did it mathematically.
5/7*10/10 = 50/70
8/10*7/7 = 56/70
Now that the denominators are the same, you can compare 50 to 56 and obviously, 50 is smaller than 56.
Hope this helps! If you have any questions, just ask!
