Answer:

No. The difference is 1 7/12 not 1 2/3.

Step-by-step explanation:

3 1/4 = (4x3+1)/4 = 13/4

1 2/3 = (3x1+2)3 = 5/3

LCM = 12

13/4 = 39/12

5/3 = 20/12

39-20=19

19/12 = 1 7/12.

The flour is 1 7/12 cups more than Sugar, So Emily's statement is false.

Given:

Emily uses 1 2/3 cups of sugar and 3 1/4 cups of flour to make muffins.

She says she has 1 2/3 more cups of flour than sugar.

To find:

Do you agree? Explain.  

Solution:

From the data,

Emily uses 1 2/3 cups of sugar and 3 1/4 cups of flour to make muffins.  

For simple calculations convert the above fractions into improper fractions as follows

1 2/3 cups = 5/3 cups   [ (3 × 1) + 2 = 5 ]  

3 1/4 cups = 13/4 cups   [ (4 ×3) + 1 = 13 ]  

Now find the difference between both measurements

=> 13/4 - 5/3

=> [ 13(3) - 5(4) ]/12     [ Take LCM of 3 and 4 as 12 ]

=> [ 39 - 20]/12

=> 19/12    

Here 19/12 = 1 7/12

Hence,

The flour is 1 7/12 cups more than Sugar, So Emily's statement is false.
