How to cross multiple 3/5 by 10

Vika [28.1K]

Here is you're answer:

In order to cross multiply you have to multiply the numerator and denominator of the first fraction by the bottom number of the second fraction and see if the equation is still true:

$\frac{3}{5} \times 10$
$\frac{3}{5} \times \frac{10}{1}$
$3 \times 1 = 5 \times 10$
Solve if you like:
$3 \times 1 = 3$
$5 \times 10 = 50$
$= \frac{4}{50}$

Therefore you're answer is "3 × 1 = 5 × 10."

Hope this helps!

How do you write 40/25 as a percentage?

rosijanka [135]

What percent of 40 is 25?
Let x = what percent
of = multiplication
is means =
We now write it in math terms:
x times 40 = 25

40x = 25
Divide both sides by 40 to find x.
x = 25/40
x = 0.625
Change the decimal number 0.625 to a percent.
x = 62.5%

Marisa bought four bottles of water.Each bottle of water was 95 cents. Write an equation with the same product as the total cost

meriva

Answer:

$5\times 0.76= 3.8$

Step-by-step explanation:

Given: Marisa bought four bottles

Price of each bottle is $0.95.

Solving with the factors as given to find the total cost paid by Marisa.

Total cost= $4\ bottles\times \$ 0.95= \$ 3.8$

∴ Total cost paid by Marisa is $3.8.

As given to write an equation with the same product as the total cost but different factors.

∴ Lets assume the number of bottles bought by Marisa be "5" and cost of each bottle be "x"

We already find the total cost she paid is $3.8.

Now, writing an equation with different factors, as total cost remain same.

$5\times x= 3.8$

Dividing both side by 5

we get x= $ 0.76

∴ The required equation is $5\times 0.76= 3.8$
