Last year it rained 2 and 1/2 in. in April and 1 and 1/3 in. in May. What is the total rainfall for the two months?
A:2 and 10/12 in
B:3 and 2/5 in
C: 3 and 5/6
D: 3 and 1/2 in
millie is right
3 5/6 is the answer
2 6/12 + 1 4/12 = _________
man this website had all these answers years ago this is so old like sheeeesh
To find the total rainfall for the two months, you need to add the rainfall in April and May together.
In April, it rained 2 and 1/2 inches, which can be written as a mixed number 2 + 1/2. To add this to the rainfall in May, you need to have the same denominator for both fractions.
To achieve this, convert the mixed number 2 + 1/2 into an improper fraction. Multiply the whole number (2) by the denominator (2), then add the numerator (1). This gives you (2 * 2) + 1 = 5. So, the improper fraction for 2 and 1/2 is 5/2.
In May, it rained 1 and 1/3 inches, which is already a mixed number.
Now, add the two fractions together: 5/2 + 4/3.
To add these fractions, you need to find a common denominator. In this case, the common denominator is 6 because both 2 and 3 divide evenly into 6.
Now, convert both fractions to have a denominator of 6.
For 5/2, multiply both the numerator and denominator by 3 to get 15/6.
For 4/3, multiply both the numerator and denominator by 2 to get 8/6.
You can now add the fractions: 15/6 + 8/6.
Add the numerators together: 15 + 8 = 23.
So, the total rainfall for the two months is 23/6 inches.
To simplify this fraction, divide the numerator by the denominator. 23 divided by 6 equals 3 with a remainder of 5.
Therefore, the simplified fraction is 3 and 5/6.
Therefore, the correct answer is C: 3 and 5/6 inches.
