Question

Sara made cupcakes. She used 2 ⅔ cups
of flour and 1 ½ cups of sugar. How much
more flour than sugar did she use?

Answer 1

Answer:

Step-by-step explanation:

2 2/3 - 1 1/2

2 2/3 = 8/3 (mixed fraction to improper fraction)

1 1/2 = 3/2  (mixed fraction to improper fraction)

8/3 - 3/2

LCM of 3 and 2 = 6

8/3  -  as 3 x 2 is 6, multiply 8 and 2 = 8 x 2/ 3 x 2 = 16/6

3/2  -  as 2 x 3 is 6, multiply 3 and 3 = 3 x 3 / 2 x 3 = 9/6

16/6 - 9/6

7/6

∴ Sara used 7/6 more flour than sugar.
