Roger has 2 1/2 cups of butter. A recipe for a loaf of bread requires 3/4 cups of butter. How many loaves can Roger bake?

lubasha [3.4K]

The number of loaves can be determined with dividing the butter by the number of cups needed for a loaf.
loaves = 2 1/2 ÷ 3/4

Change into improper fraction
loaves = 2 1/2 ÷ 3/4
loaves = 5/2 ÷ 3/4

Change into multiplication
loaves = 5/2 ÷ 3/4
loaves = 5/2 × 4/3
loaves = 20/6
loaves = 10/3
loaves = 3.3
Because the number of loaves can't be a fraction, round it to the smaller whole number

Roger can make 3 loaves of bread

DiKsa [7]

Answer: The different possible solutions are 42, 21, 31 and 80.

Explanation:

The given expression is,

$7+3\cdot 4+2$

Case 1.

$(7+3)\cdot 4+2=10\cdot 4+2$

$(7+3)\cdot 4+2=40+2$

$(7+3)\cdot 4+2=42$

Case 2.

$7+(3\cdot 4)+2=7+12+2$

$7+(3\cdot 4)+2=21$

Case 3.

$7+3\cdot (4+2)=7+3\cdot 8$

$7+3\cdot (4+2)=7+24$

$7+3\cdot (4+2)=31$

Case 4.

$(7+3)\cdot (4+2)=10\cdot 8$

$(7+3)\cdot (4+2)=80$

rewona [7]

<u />the answer may be 125 because 20 pieces of colored paper is only part and then the whole would be 125 because divided by is 5 so 25 times 5 is 125.
