Mr. Klimek made his wife a rectangular vegetable garden. The width is 5 3/4 ft, and the length is 9 4/5 ft. Mr. Klimek calculated his garden to be 15 11/20 square feet. Is Mr. Klimek correct with his calculations? If he is, what did he do to find his answer. If he is incorrect, what did he specifically do wrong, what is the correct answer? Show and Explain.

He is wrong. The right answer is 56.35. Or 56 7/20

Step-by-step explanation:

So lets go over what we know.

The width is 5 3/4ft.

The length is 9 4/5 ft.

The square feet is l*w, otherwise known as area.

So in this, we multiply 5 3/4 by 9 4/5.

Before we multiply however, lets put this into decimal form. Its easier to think of it this way.

3/4, or 3 divided by 4, is 0.75 So 5 3/4 is actually 5.75

4/5, or 4 divided by 5, is 0.80. So 9 4/5 is actually 9.8

Now lets multiply:

5.75*9.8

This might seem a bit confusing, but here is a step by step way of how I multiplied:

5*9 is 45. 5 times 8 is 40. Move the decimal since we used 8 instead of .8 its now:

45 and 4.0

Which is 49.

Now lets multiply 9.8 by the 0.75

3/4ths of 9 is 6.75. 3/4 of 8 is 6. Again, move over the decimal since we used 8 instead of .8 its now:

6.75 and .6

This is 7.35

Add that to 49:

56.35

So this is your answer.

Now, this is not what Mr.Klimek got.

So he is wrong.

The real answer is 56.35

To find the fractional form of this, we can take the decimal 35 and put it over 100:

35/100

Then simplfy. In this case 5 goes into both numbers. So:

7/20

So we have 56 7/20.

Now, the final question, what did Mr.Klimek do wrong?

Well, he added his length and width, instead of multiplying.

We already know what our two numbers equal: 9.8 and 5.75.

Lets add these:

9 plus 5 is 14. 0.8+0.75 is 1.55.

14+1.55=15.55

Using the method of transfering  fractions I spoke of above:

55/100

5 goes into both numbers:

11/20

So adding the lenght and width, we got 15 11/20. This is what Mr.Klimek did.

So to sum up each

Hope this helps! :D

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
