What is the answer to 2/3+3/5?

Question

math problem

Answer 1

10 / 15 + 9 / 15 = 19 / 15 = 1 4/15

Answer 2

= 2/3 + 3/5
= 10/15 + 9/15
= 19/15
= 1 4/15

Answer 3

2/3 + 3/5
= 2*5/3*5 + 3*3/5*3
=10/15 + 9/15
=(10 + 9)/15
= 19/15

Answer 4

It's kind of hard to add thirds and fifths...

But, would you accept that if I multiply 2/3 by 1 I still have 2/3? And would you accept that if I multiply 3/5 by 1 I still have 3/5?

I hope you do, because that's one of the properties of 1.

So, what happens if I multiply 2/3 by 5/5... 5/5=1, right?
2/3 x 5/5 = 1015... but it's still equal to 2/3... right?

And what hapens when I multiply 3/5 by 3/3.... 3/3 is also = 1, right?
3/5 x 3/3 = 9/15... but it's still equal to 3/5... right.

Now the problem is
2/3+3/5
But we can now use
10/15 + 9/15 because we've decided that the fractions are equivalent.

Can you add 10/15 and 9/15?

Explanation:
I chose 5/5 to multiply 2/3 by because 5 was the denominator of the other fraction. It's the same reaons I picked 3/3 to multiply 3/5 by.

15 is called a "common denominator." In this case it's the"Lowest Common Denominator" because it's the lowest number both 3 and 5 divide into evnly.

Answer 5

Before you can add two fractions, the denominators must be the same. This can be done using a simple formula:
A/B + C/D
= [AD + BC] / BD

so 2/3 + 3/5
= [2(5) + 3(3)] / 3(5)
= [10 + 9] / 15
= 19 / 15
= 1 4/15

Answer 6

2/3 + 3/5
lcd is 15
3times 5 = 15
5times 2 = 10
5times 3 =15
3times 3 = 9 5*2=10, 3*3 = 9
therefore, (10+9)/15
19/15 =

Answer 7

You cannot add or subtract fractions unless the denominators are the same. NEVER!
2/3+3/5
Lowest common denominator is 3 X 5 =15
10/15+9/15=19/15

Answer 8

To add fractions with different denominators, you first need to find a common denominator. A quick-and-dirty way to do this (without finding the least common denominator, LCD), is to multiply each fraction by 1, expressed as denominator/denominator.

Say you'd like to add
a/b + c/d

The first step is to multiply both parts by 1
a/b*d/d + c/d*b/b

You can now commute some of the factors, to get
(a*d)/(b*d) + (b*c)/(b*d)

Now we have a common factor we can pull out of both, 1/(b*d)
(a*d+b*c)*(1/(b*d))

And so we get
(a*d+b*d)/(b*d)

To specifically address your question:
2/3 + 3/5
== 2/3*5/5 + 3/5*3/3
== 10/15 + 9/15
== 19/15

Answer 9

(10 +9)/15 = 1 4/15

Answer 10

this is not to bad
(10+9)/15= 19/15
this should be correct!
