Question

4/6 cup of flour .the recipe calls for 1/4 cup of flour .how much flour would you have left if you made the bread would i use subtraction ?

Answer 1

yes...use subtraction, but make sure you get a common denominator for the two fractions before subtracting.

Answer 2

also, you might want to reduce 4/6...4/6 = 2/3

Answer 3

so its now 4/6- 1/4=whats the common demoninator ?

Answer 4

reducing first, you have 2/3 - 1/4.

What is the smallest number that is divisible by both 3 and 4?

Answer 5

yes, you would use subtraction. you need the get the least common denominator, which in this case is 12.

(4/6)2 and (1/4)3. you should end up with (8/12)-(3/12)

you'll end up with 5/12

Answer 6

did that help?

Answer 7

so 12 is the lcd

Answer 8

yes

Answer 9

yes that did help

Answer 10

is 2/4+1/5=14/20?

Answer 11

14/20 can reduce.

if you start out with 2/4 = 1/2, you don't need to redduce in the end.

2/4 + 1/5 = 1/2 + 1/5 = 5/10 + 2/10 = 7/10

Answer 12

Your answer of 14/20 was correct...but not finished. In my opinion, getting the correct answer as you did is the hardest part :)
