Question

add the following fractions 2 over 15 + 1 over 3

Answer 1

[AI-generated answer — Bot GPT 3.5]

To add these fractions, first, we need to find a common denominator. In this case, the common denominator is 15.

2/15 + 1/3 = (2/15) + (5/15)

Now that the fractions have the same denominator, we can simply add the numerators:
= (2 + 5)/15
= 7/15

Therefore, 2/15 + 1/3 = 7/15.

Answer 2

solve and simplify 19 over 25 - 4 over 25

Answer 3

To solve and simplify the expression 19/25 - 4/25, we can directly subtract the numerators since the denominators are the same.

(19 - 4)/25 = 15/25

To simplify this fraction, we can find a common factor of 15 and 25, which is 5.

15/25 = (15 ÷ 5)/(25 ÷ 5)

= 3/5

Therefore, 19/25 - 4/25 = 3/5.

Answer 4

solve and simplify 17/35 - 10/35

To solve and simplify the expression 17/35 - 10/35, we can directly subtract the numerators since the denominators are the same.

(17 - 10)/35 = 7/35

To simplify this fraction, we can find a common factor of 7 and 35, which is 7.

7/35 = (7 ÷ 7)/(35 ÷ 7)

= 1/5

Therefore, 17/35 - 10/35 = 1/5.

Answer 6

explain why you cannot add or subtract fractions with unlike denominators while you can add or subtract fractions with like denominators include one or more real world examples in your explanation make it short and write it like 5th grader

When adding or subtracting fractions, the fractions need to have the same denominator in order to be combined. This is because the denominator tells us how many equal parts the whole is divided into.

For example, let's say you have 3 pizzas, each divided into 8 equal slices. If you have 2 of those slices, you can add them together because they have the same denominator (8/8 + 4/8 = 12/8). You can think of it as adding 2 slices to 4 slices to get a total of 6 slices of pizza.

However, if you have another pizza where the slices are divided into 12 equal parts, you cannot add those slices directly to the previous slices. This is because the denominators are different (8 and 12), meaning the slices are of different sizes. It's like trying to add 2 apples to 3 oranges – they are different things!

So, in order to add or subtract fractions, we need to make sure they have the same denominator first.

When adding or subtracting fractions, the denominators need to be the same because they represent the number of equal parts the whole is divided into. This allows us to properly combine the fractions and make accurate calculations.
