Question

can someone help me figure this out ??

Answer 1

I assume you attaching something - correct ?

Answer 2

yes a recipe calls for 2/4 cup of onion and 1/5 chopped
celery what is the total amount ?

Answer 3

im think i should find a common denominator ?

Answer 4

total amount of onion and celery combined ?

first notice that you can reduce the 2/4 , right ?

Answer 5

yes u can

Answer 6

and you get ?

Answer 7

you can divide the nominator and denominator by 2, so:
2/4 = ?

Answer 8

don't reduce it, that's just extra unneccesary work. You need to find GCD in order to make the denominators the same, then just add the numerators and simplify if necessary

Answer 9

what is the smallest number that is divisible by both 4 and 5?

Answer 10

pretty much same thing as where fiddle is headed, but just switching early step for later step

Answer 11

2?

Answer 12

yup, now, what's the smallest number that is divisible by both 2 and 5?

Answer 13

so now you have

1/2 + 1/5

Answer 14

the greatest common denominator is 10, it can be divided evenly by both 2 and 5.

Answer 15

so, you divide 10 by each denominator, and then take the result for each denominator and multiply by the respective fraction.
so:
now you should have 1/2 * (5/5) + 1/5 * (2/2) = 5/10 + 2/10
now since they have same denominator, you can just add the numerators to get your answer. Then you can simplify, but in this case it is not necessary, the answer is already in simplest form

Answer 16

my answer is 2/10?

Answer 17

???

Answer 18

5/10 + 2/10 = 7/10
7/10 is answer

i think you just forgot the first fraction

Answer 19

there's more than one way to do it but you should always get the same answer in the end
