Convert 4.2% to an equivalent decimal.

hjlf

Answer:

4.2% = 0.042

Step-by-step explanation:

You need to divide the percentage by 100 to get its equivalent decimal:

100% = 1 because

100 ÷ 100 = 1

Therefore,

4.2% = 0.042 because

4.2 ÷ 100 = 0.042

Hope this helped :)

nataly862011 [7]

Answer:

$L=\frac{15}{16}\ yd$

Step-by-step explanation:

The correct question is

Devon needs a wood board with an area of 5/16 square yard to complete a project. If the wood board is 1/3 yard wide, how long must the board be?

we know that

The area of a rectangle is equal to

$A=LW$

where

L is the length

W is the width

we have

$A=\frac{5}{16}\ yd^2\\\\W=\frac{1}{3}\ yd$

substitute

$\frac{5}{16}=L(\frac{1}{3})$

solve for L

$L=\frac{5}{16}(3)$

$L=\frac{15}{16}\ yd$
