Answer:

50 is the old value and 23 is the new value. In this case we have a negative change (decrease) of -54 percent because the new value is smaller than the old value. Using this tool you can find the percent decrease for any value.

Isabella painted her bedroom. She used 2 gallons of paint and finished in 8 hours. At what rate did Isabella paint the room?

GrogVix [38]

Answer: " \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " .

_______________

Step-by-step explanation:

_______________

This is a "unit rate" problem;

that is: we want to solve for a particular quantity per [single] unit.

_______________

→ in this case, per single "hour" ;

_______________

So we convert:

_______________

" 2 gal per 8 hours" ; to the correct number of:

_?_ gal per [single] hr.

_______________

{<u>Note</u>: "gal" refers to: "gallon(s)" ;

"hr" refers to: "hour(s)" .}.

_______________

→ " $\frac{2 gal}{ 8 hr} = [\frac{2}{8}]$ gal / hr. " ;

_______________

→ " { $\frac{2}{8} =$ [2÷2] / [8÷2] = 1/4 ;

_______________

So, the answer is:

→ " $\frac{1}{4} gal /hr$ " ;

_______________

or: write as decimal:

→ " $\frac{1}{4}$ = (1 ÷ 4) = 0.25 " ;

_______________

write the answer as:

_______________

→ " 0.25 gal/hr. "

_______________

Or, when we had:

→ "2/8" gal/hr ;

_______________

Use calculator:

→ " $\frac{2}{8}$ = "2 ÷ 8" ;

= " 0.25 gal/ hr.

_______________

So: The correct answer is:

_______________

" \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " ;

_______________
