2 answers:

8 0

A unit fraction is a fraction where the denominator is one, so the easiest way to write 4/5 as a sum of unit fractions is to use 1/5.
So the answer would be 1/5+1/5+1/5+1/5.
Add up all the numerators and put that over their like denominators to get 4/5!

Answer:

$\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}$

Step-by-step explanation:

we know that

A unit fraction is a fraction with a numerator equal to $1$

In this problem we have

$\frac{4}{5}$

rewrite as a sum of unit fractions

$\frac{4}{5}=4*\frac{1}{5}=\frac{1}{5}+\frac{1}{5}+\frac{1}{5}+\frac{1}{5}$

Rasek [7]

Answer: the total cost of the meal is

$17.7415

Step-by-step explanation:

The original cost of the breakfast $10.25 and the original cost of the coffee is $3.45. This means that the total cost of the breakfast and the coffee was

10.25 + 3.45 = $13.7

You leave a 20% tip. This means that the amount of tip that you left is

20/100 × 13.7 = 0.2 × 13.7 = $2.74

The sales tax is 9.5%. This means that the amount of sales tax that you paid is

9.5/100 × 13.7 = 0.095 × 13.7 = $1.3015

Therefore, the total cost of the meal would be

13.7 + 2.74 + 1.3015 = $17.7415

The length of a rectangle is three times its breadth if the breadth is decreased by 2 m and breadth increased by 4 m the area of

White raven [17]

Answer:

Let the breadth is x, then the length is 3x.

The area is:

A = lw = 3x*x = 3x²

The breadth is decreased by 2 m:

w = x - 2

The length is increased by 4m:

l = 3x + 4

The area is now:

(x - 2)(3x + 4) = 3x² - 1/3(3x²)
3x² + 4x - 6x - 8 = 2x²
x² - 2x - 8 = 0
x² - 2x + 1 = 9
(x - 1)² = 3²
x - 1 = 3
x = 4

The breadth was 4 m and the length 12 m

Ruben put an empty cup underneath a leaking faucet. After 1 1/2 hours, Ruben had collected 1/4 cup of water. What is the rate, i

worty [1.4K]

Answer:

The rate is $\frac{1}{6}$ cups per hour

Step-by-step explanation:

It took the faucet 1 1/2 hours, i.e 1.5 or 3/2 hours to fill 1/4 cup by leaking

We need to find the rate in terms of cups that can be filled by water in 1 hour.

Using unitary method:

If it takes $\frac{3}{2}$ h for $\frac{1}{4}$ cup;

then it will take 1 h for how many cups?

$= \frac{1 \times \frac{1}{4} }{\frac{3}{2} }$

$= \frac{2}{4 \times 3}$

$= \frac{2}{12}$

$= \frac{1}{6}$ cups

Therefore, the rate is $\frac{1}{6}$ cups per hour

Ilya [14]

Answer:

Step-by-step explanation:

At a Baseball Match.

35% of spectators are New York Yankees fan

The rest are Boston Red Sox fan = 100 - 35% = 65%

30% of fans in both teams are females.

30% of 35% of spectators are New York Yankees fan = 0.105 females

30% of 65% of spectators are Boston Red Sox fan = 0.195 females

The number of males in New York Yankees fan = 1 - 0.105 females

= 0.895 males

The number of males in Boston Red Sox fan = 1 - 0.195 females

= 0.805 males
