tester [92]

Lenght is 4 1/2 cm
P=2L +2W
15cm = 2L + 2(2/3L)
15cm = 2L + 4/3L
15cm = 2 4/3 L
15cm ÷ 2 4/3 = 2 4/3L ÷ 2 4/3
4 1/2cm = L

Check
P=2L +2W
P=2(4.5) +2(3)

(01.05 LC)Which fraction is equivalent to negative 3 over 7? negative 7 over 3 3 over negative 7 3 over 7 7 over 3

Kitty [74]

Answer:

Second option

Step-by-step explanation:

Given the following question:

$-\frac{3}{7}$

In order to find the answer, we will apply the fraction rule.

$\frac{a}{-b} =-\frac{a}{b}$
$\frac{3}{-7} =-\frac{3}{7}$
$=\frac{3}{-7}$

Not the third or fourth option because negatives do not equal a positive. It's also not option A because....

$-\frac{7}{3} =7\div3=-2\frac{1}{2}$

Your answer is indeed the second option.

Hope this helps.
