Question

Angela had 2 cups of flour. She used 1 and 1/4 cups when making muffins. Angela says she has 3/4 cup of flour left. Is Angela's answer reasonable? A. No, her answer is not reasonable because 2 * 1 and 1/4=2 and 1/2 B. No, her answer is not reasonable because 2+1 and 1/4 =3 and 1/4. C. Yes, her answer is reasonable because 2-1 and 1/4=3/4

FIRST ANSWER WHO IS RIGHT WILL GET BRAINILEST .

Answer 1

Subtract the amount used from the total:

=2 cups - 1 1/4 cups
convert from mixed number to an improper fraction

= 2 - 5/4
convert to a common denominator; 2 is the same as 2/1

= 2/1 - 5/4

= 8/4 - 5/4

= 3/4 cup of flour left


ANSWER: (C) Yes, her answer is reasonable because 2 - 1 3/4= 3/4

Hope this helps! :)
