Question

evaluate using order of operations

Answer 1

Hey there!
Sorry for replaying a little late :-/

did you know that people on the computers viewing the question might not be able to see the picture that you linked?

anyways, the order of operations is:
PEMDAS

so for your question, we should multiply
2/5 and 4/9 first

Answer 2

that should get us

4 • 2 = 8
and
5 • 9 = 45

so (2/5) • (4/9) = (8/45)

Answer 3

then we should add the fractions left to right

(19/24) + (21/10) = ?
[remember that you need a common denominator]
then add (8/45) to that

and that should get you to the answer :)


Sorry again for the late reply and I hope I was able to help!
