Question 3(Multiple Choice Worth 2 points)
(10.04 LC)
Round each fraction to help you estimate the solution for the following equation:
nine tenths minus four tenths equals
0
one half
1
one and one half
.9 - .4 = .5
To estimate the solution for the equation "nine tenths minus four tenths," we can round each fraction.
The round of nine tenths would be 1, and the round of four tenths would be 0. Therefore, the estimated solution is:
1 - 0 = 1
To round each fraction and estimate the solution for the given equation, we first need to subtract the two fractions involved.
The equation is "nine tenths minus four tenths."
To subtract the fractions, we need to have a common denominator. In this case, the denominators of both fractions are already the same (tenths).
Now, we can subtract the numerators:
9 - 4 = 5
So, the result is 5 tenths.
To round this result, we need to determine its proximity to the nearest whole number or half.
Since 5 tenths is halfway between 0 and 1, we can round it to the nearest half, which is one half.
Therefore, the estimated solution for the equation "nine tenths minus four tenths equals" is:
one half.
