Answer:
Step-by-step explanation:
We need to find the error first.
We can do this by subtracting, to find the difference
2.4-1.9 = 0.5
the difference, or error, is 0.5
Now we find a percentage that describes how much more 2.4 is than 1.9
We can create an equation to solve this
2.4 = 1.9 Times x
Now we need to find the value of x
x= 1.2632
now we double check
1.9 Times 1.2632 = 2.4
Now we round to a whole number
1.2632 = 1
To convert a number to a percentage, you need to bring the number over a decimal point.
so 1 becomes .1, or 10 percent
