Write the fraction 14/3 as the product of a whole number and a unit fraction.

How do I write the fraction? Please help! I will give brainliest if 2 or more people answer :)

Answers

Answer:

The unit fraction is 1/3 and the whole number is 4 2/3 however its a mixed fraction so I'm not positive about it so you could make just use the 4 as a whole number.

Step-by-step explanation:

The unit fraction is written using a numerator of 1 and keeping the original denominator. So it would be 1/3. 3 goes into 14 4 times so you get the four there. however there is still 2/3 as 3 cannot go into 2. however if you would like to you can convert 2 divided by 3 into a decimal or 0.666666667.

Use 4 as a whole number hope this was right and it would mean the world to me if I could have brainliest

Answer: C) =

Step-by-step explanation: You can convert -14/4 from a fraction into a decimal. Take the denominator, 4, how many times does it go into the numerator, 14? 4 goes into 14 exactly 3.5 times. So, that means if the fraction was -14/4, you need to take that negative sign and put it in front of your decimal. Once you do that, you see that both the first and second number turn out to be the same number, -3.5. Therefore, your answer is C, as the numbers are equal to one another.

Find the area of the composite figure. Don't forget to use the word "square" and then the given units in your answer

Answers

i got 147 ft squared
your answer would be 147 square feet!!

this is because if you break the composite figure into two rectangles, they would be

rectangle 1:
7 (width) x 13.5 (height) = 94.5 sq ft

rectangle 2:
15 (width) x 3.5 (height) = 52.5 sq ft


then, when you add both areas,

94.5 + 52.5

the total area is,

= 147 square feet
