First -- Get rid of the all-caps typing and misspelled words in your screen name space. Just a name so you can find your own post again is all that's needed.
Second -- Copy and paste your problems into www.google.com and see what happens.
Let us know what you learn.
theres my new name and thats pretty cool thanks
You're welcome.
1.
2 / 5 = 2 * 2 / ( 5 * 2 ) = 4 / 10
4 2/5 = 4 + 2 / 5 = 4 + 4 / 10 = 4 * 10 / 10 + 4 / 10 = 40 / 10 + 4 / 10 = 44 / 10
1 7/10 = 1 + 7 / 10 = 10 / 10 + 7 / 10 = 17 / 10
4 2/5 - 1 7/10 = 44 / 10 - 17 / 10 = 27 /10 = 20 / 10 + 7 / 10 = 2 7/10
2.
5 2/3 = 5 + 2 / 3 = 5 * 3 / 3 + 2 / 3 = 15 / 3 + 2 / 3 = 17 / 3
2 1/3 = 2 + 1 / 3 = 2 * 3 * 3 + 1 / 3 = 6 / 3 + 1 / 3 = 7 / 3
5 2/3 - 2 1/3 = 17 / 3 - 7 / 3 = 10 / 3
10 / 3 = ( 9 + 1 ) / 3 = 9 / 3 + 1 / 3 = 3 1/3
OR
5 2/3 - 2 1/3 = 5 - 2 + 2 / 3 - 1 / 3 = 3 + 1 / 3 = 3 1/3
To solve the first problem, we need to subtract the given mixed numbers: 4 2/5 - 1 7/10.
Step 1: Convert the mixed numbers into improper fractions.
4 2/5 = (4 * 5 + 2) / 5 = 22/5
1 7/10 = (1 * 10 + 7) / 10 = 17/10
Step 2: Find a common denominator for the fractions. In this case, it is 10.
22/5 = (22/5) * (2/2) = 44/10
17/10 = 17/10
Step 3: Subtract the fractions.
44/10 - 17/10 = (44 - 17) / 10 = 27/10
Step 4: Convert the result back to a mixed number.
27/10 can be written as 2 7/10.
Therefore, the correct answer to the first problem is A. 2 7/10.
Now let's move on to the second problem: 5 2/3 - 2 1/3.
Step 1: Convert the mixed numbers into improper fractions.
5 2/3 = (5 * 3 + 2) / 3 = 17/3
2 1/3 = (2 * 3 + 1) / 3 = 7/3
Step 2: Subtract the fractions.
17/3 - 7/3 = (17 - 7) / 3 = 10/3
Step 3: Convert the result back to a mixed number.
10/3 can be written as 3 1/3.
Therefore, the correct answer to the second problem is B. 3 1/3.
Based on your answers:
1. Your answer is incorrect. The correct answer is A. 2 7/10.
2. Your answer is correct. The correct answer is B. 3 1/3.
Remember to double-check your calculations and pay attention to the conversion between mixed numbers and improper fractions to ensure accurate results.
