What is the solution to 4w=2/3

Answers

2/12 or 1/6. You have to divide 2/3 by 4 to get what w equals to.
4w = 2/3 Divide each side by 4 to get w by itself.

w = 2/3 ÷ 4 To divide fractions you multiply the reciprocal

w = 2/3 × 1/4 multiply across

w = 2/12 which reduces

w = 1/6

How do you solve the answer to this
-6(-3)(-2)

Answers

so if 2 number with the same sign are multiplied togher, the result will be positive
so if (-) times (-)=(+)
and (+) times (-)=(-)
then
(-) times (-) times (-)=(-)

so just multiply them so
-6 times -2=+12
+12 times -3=-36


First of all, a negative times a negative times a negative would end up as a negative, so we got that covered. Now all we need is the arithmetic part. 6 x 3 = 18, and 18 x 2 = 36 

So you're final answer would be -36

Tomas drew a rectangular with an area of 6 square centimeters. What is the greatest possible perimeter for this rectangle

Answers

There is no "greatest" possible perimeter.

There's a smallest possible perimeter.  That's a square.
Since the area is 6 square centimeters, each side of the square is
√6 = about 2.45 cm, and the perimeter is about  9.8 cm (rounded).

But there's no 'greatest' perimeter.  You can take that square
and if you're careful, you can make it into rectangles that all have
the same area ... 6 square cm ... but the longer and skinnier
you make it, the greater the perimeter will be. 
You can give me a number as big as you want, and I can make
a rectangle with a perimeter of your number, but an area of only
6 square centimeters !

Here are some few examples.  They all have
the same area, but different perimeters:

2.45 cm by 2.45 cm ...   Area = 6 square cm ... Perimeter = 9.8 cm

2 cm by 3 cm ...              Area = 6 square cm ... Perimeter = 10 cm
1.5 cm by 4 cm ...           Area = 6 square cm ... Perimeter = 11 cm
1.2 cm by 5 cm ...           Area = 6 square cm ... Perimeter = 12.4 cm
1 cm by 6 cm ...              Area = 6 square cm ... Perimeter = 14 cm
0.8 cm by 7.5 cm ...        Area = 6 square cm ... Perimeter = 16.6 cm
0.6 cm by 10 cm ...         Area = 6 square cm ... Perimeter = 21.2 cm
0.5 cm by 12 cm ...         Area = 6 square cm ... Perimeter = 25 cm
0.4 cm by 15 cm ...         Area = 6 square cm ... Perimeter = 30.8 cm
0.3 cm by 20 cm ...         Area = 6 square cm ... Perimeter = 40.6 cm
0.2 cm by 30 cm ...         Area = 6 square cm ... Perimeter = 60.4 cm
0.1 cm by 60 cm ...         Area = 6 square cm ... Perimeter = 120.2 cm

0.001cm by 6,000cm ... Area = 6 square cm ... Perimeter = 12,000.2 cm
