Question

Kandice notices that 2/7 of a gallon of milk is on the top shelf of the refrigerator, and 3/5 of gallon of milk is on the bottom shelf. How much milk is in the refrigerator in all?

Answer 1

make the denominators the same

Answer 2

so lets make the denominator 5*7=35, right?

Answer 3

to do that, you need to multiply both the numerator and denominator of 2/7 by 5, remember what you do to the top you must do to the bottom

Answer 4

so you have 10/35

Answer 5

then you need to multiply both in 3/5 by 7, so you have 21/35

Answer 6

you following?

Answer 7

yes a little

Answer 8

k do you understand what ive done so far?

Answer 9

yes

Answer 10

to add them, the bottom number of both fractions have to be common, and the easiest way to find the common denominator is just to multiply them by each other

Answer 11

so now that youve found the common denominator and multiplied both fractions by the required number, just add the fractions together

Answer 12

\[\frac{ 10 }{ 35 }+\frac{ 21 }{ 35 }\]

Answer 13

31/35 of a gallon
at this point you would simplify if you could, but you cant simplify this
