Emily is comparing different discounts offered at a local store. Which statement about the different discounts is true? * 1 point 2/5 = 1. 0.4 = 40% 2. 0.20 = 1/20 = 20% 3. 3/10 = 0.03 = 3% 1.3 = 4/3 = 75%

Answer and Step-by-step explanation:

Here the person is comparing discounts by using percentages, fractions and decimals that are supposed to be the same amounts

Decimal number is example 0.22

Percentage is example 5%

Fraction is example 5/9

1. Statement one is incorrect:

2/5 is not equal 1, 2/5= 0.4

40%= 40/100=0.4

2. Statement two is incorrect, although 0.20= 20% because 20/100= 0.20=20%

1/20 = 0.05 and not equal to the percentage and decimal number

3. Statement three is incorrect because although 0.03= 3% because 3/100= 0.03=3%

3/10= 0.30 =30% and is therefore nor equal to the percentage and decimal number

4. Statement 4 is incorrect because although 4/3 = 1.3, 75% is 75/100= 0.75 and therefore not equal to the fraction and decimal number

Note : statement 1 might be a typo because 2/5=0.4=40% so the 1 might be a typo

step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
