John dana and douglas painted a room
they have combined effort so
john+dana+douglas=total room

total room=100%=1/1=1
so 1 whole=8/8 so
2/8 is painted by john so they don't need to paint that so
so
2/8+dana+douglas=8/8
subtract 2/8 frm both sides
dana+dogluas=(8-2)/8=6/8
dana+douglas=6/8
dana painted same as douglas so divide by 2
dana=douglas=3/8

so A is 6/8 or 3/4
B is 2/8+3/8+3/8=8/8 or 2/8+dana+douglas=8/8

Equations which are never true :

2.1 Solve : 2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2 Solve : 2x+1 = 0

Subtract 1 from both sides of the equation :

2x = -1

Divide both sides of the equation by 2:

x = -1/2 = -0.500

One solution was found :

x = -1/2 = -0.500

46. Merchandising If 12 items are in a dozen, 12 dozen are in a gross, and 12 gross are in a great-gross, how many items are in

Andrews [41]

Answer: 1728

Step-by-step explanation: You multiply 12 times 12 because we have to find how many items are in a 12 dozen first which is 144 because there are 12 items in one dozen. We already know that there are 144 items in 12 dozens and there are 12 dozens in a gross, which is 144 items in total. Now we have to multiply 144 times 12 to find how many items are in a great gross. 144 times 12 is 1728.

61% of 180 ?

poizon [28]

First, when multiplying percents, you need to convert them to decimals. You convert percents to decimals by multiplying by 100 or moving the decimal two places to the left. Once you convert them to full decimals, you multiply the decimal by the number that you are getting the percentage from

61% of 180⇒.61×180=109.8 

5.1% of 81?⇒.051×81=4.131

 $16 \frac{1}{2}$ of 36?⇒16.5×36⇒.165×36=5.94

81% of 241⇒.81×241=195.21

76% of 600⇒.76×600=456

88% of 680⇒.88×680=598.4

37% of 481⇒.37×481=177.97

19.1% of 380⇒.191×380=72.58

41% of 321⇒.41×321=131.61

33% of 331⇒.33×331=109.23
