Question

Adrienne has 20 cups of flour she used 7 3/4 cups of flour for a batch of bread and 3 1/3 cups of flour for a batch of cookies how much flour did Adrienne have left after she baked the bread and cookies

Answer 1

The answer to your question is: 8 11/12

Explanation:

Data

Total cups = 20

cups used for bread = 7 3/4

Cups for cookies = 3 1/3

Process

Convert mixed fraccions to improper fractions

7 3/4 =
`(28 + 3)/(4)  = (31)/(4)`

3 1/3 =
`(9 + 1)/(3)  = (10)/(3)`

Cups left = total cups - cups for bread - cups for cookies

Cups left = 20 -
`(31)/(4)  - (10)/(3)`

Cups left =
`(240 - 93 - 40)/(12)`

Cups left =
`(107)/(12)`

Cups left = 8 11/12

Answer 2

TOTAL NUMBER OF CUPS OF FLOUR OWNED BY ADRIENNE=20

NUMBER OF CUPS USED FOR A BATCH OF BREAD=7,3/4

NUMBER OF CUPS USED FOR A BATCH OF COOKIES= 3,1/3

TOTAL NUMBER OF USED FLOUR= CUPS USED FOR BATCH OF BREAD + BATCH USED FOR COOKIES

THIS IS =7,3/4 + 3,1/3

ADD UP THE WHOLE NUMBERS WHICH IS 7+3=10

ADD UP THE FRACTIONS 3/4 +1/3= 13/12= 1,1/12

10+1,1/12=11,1/12

TOTAL NUMBER OF FLOUR LEFT AFTER ADRIENNE BAKED ALL BREAD AND FLOUR = TOTAL NUMBER OF WHOLE FLOUR - TOTAL NUMBER OF USED FLOUR

FLOUR LEFT = 20 - 11,1/12 =

20-11= 9

9 - 1/12= 8,11/12

8,11/12
