45%, 15%, 40%, 80%, 65%, 30%, 90%, 25% Do any of these percentages match the fraction 2/5?
Slav-nsk [51]

Answer:

Yes, the third option (40%)

Step-by-step explanation:

Given the fraction with numerator 2 and denominator 5:

\frac{2}{5}

You can convert it from this fraction form  to a decimal number by dividing the numerator 2 by the denominator 5, obtaining the decimal number:

\frac{2}{5}=0.4

Finally, to rewrite this decimal number to percentage, you need to multiply it by 100. Then:

0.4*100=40\%

Therefore, there is a percentage that matches the fraction \frac{2}{5}. This percentage is 40%, which corresponds to the third option.

Hii I need help with these questions tyy!
9966 [12]

Answer:

(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);

Step-by-step explanation:

formula to find area is L* W = A ; meaning length multiplied by width equals to the area.

21.

using the formula to find area...

l*w=a

(7x+2)(3x-1) would be your answer

btw, don't put the "=a" at the end, since it's an expression :))

22.

since the problem states that it's a square, you can just say either...

(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
