4/10 is equal to 2/5 because if you reduce 4/10 you get 2/5 which shows that they are equal.
Because it helps to see which one is greater, For example: if you line up 0.079 and 0.127 you can easily tell that 0.0127 is greater because it is closer to a hole number. Another example: 0.1 and 0.3, obviously 0.3 is greater. in conclusion, the reason you line up the decimal points is to make it easier to see which numbers are greater, which helps you compare and order easily!
The answer is definitely a
Answer:
The area will be increased by 72 feet.
Step-by-step explanation:
4 x 6 = 24
Now we have to double those lengths.
We know that 4 x 2 is 8 and 6 x 2 is 12.
So the new equation would be: 8 x 12 = 96
Now we take the original area and subtract it by the new area.
96 - 24 = 72
Hope this helps:)
