Ok i need to know what 2 3/6 + 3 1/2 is 4-2 3/5 and 2/3*4/5 is because i forget how to do adding subtracting and mutiplying fractions

When adding/subtracting fractions, the goal is to find a common denominator. a/c + b/c = (a+b)/c

When multiplying, you can simply multiply the numerators and denominators. (a/b)*(c/d) = (a*c)/(b*d)

2 3/6 + 3 1/2

Find the common denominator.

2 3/6 + 3 3/6 = 5 6/6 = 7
_______________

4 - 2 3/5 = 3 5/5 = 2 3/5 = 1 2/5

______________________

2/3 * 4/5 = 8/15

OK THANKS EVERYONE WHO HELPED MY SISTER SAYS THANKS TOO!!!!!<3

You're very welcome.

To add or subtract fractions, follow these steps:

1. Make sure the denominators (the bottom numbers) are the same for both fractions. If they are different, find the least common multiple (LCM) of the denominators and convert the fractions to have the same denominator.
2. Add or subtract the numerators (the top numbers) together, while keeping the denominator the same.
3. Simplify the resulting fraction if necessary by reducing it to its simplest form.

Now, let's apply these steps to your first question:

Question 1: What is 2 3/6 + 3 1/2?

Step 1: Find a common denominator.
In this case, the common denominator is 6. So, convert both fractions to have a denominator of 6:

2 3/6 = (2 * 6 + 3) / 6 = 15/6
3 1/2 = (3 * 2 + 1) / 2 = 7/2

Step 2: Add the numerators together.
15/6 + 7/2 = (15 + 21) / 6 = 36/6 = 6

Therefore, 2 3/6 + 3 1/2 = 6.

Now let's move on to your second question:

Question 2: What is 4-2 3/5 and 2/3 * 4/5?

To subtract mixed numbers, follow these steps:

1. Convert the mixed numbers to improper fractions (fractions with a numerator larger than the denominator).
2. Subtract the second fraction from the first fraction.
3. Simplify the resulting fraction if necessary.

To multiply fractions, follow these steps:

1. Multiply the numerators together.
2. Multiply the denominators together.
3. Simplify the resulting fraction if necessary.

Now let's solve your second question:

Step 1: Convert 4-2 3/5 to an improper fraction.

4-2 3/5 = (4 * 5 - 2 * 5 + 3) / 5 = 21/5

Step 2: Simplify the improper fraction, if possible.

The fraction 21/5 is already in its simplest form.

So, 4 - 2 3/5 = 21/5.

Next, let's multiply the fractions 2/3 and 4/5:

Step 1: Multiply the numerators.

2/3 * 4/5 = 2 * 4 / 3 * 5 = 8/15

Step 2: Simplify the resulting fraction, if possible.

The fraction 8/15 is in its simplest form.

So, 2/3 * 4/5 = 8/15.

Therefore, 4-2 3/5 is equal to 21/5 and 2/3 * 4/5 is equal to 8/15.
