45 is 25% of a number. find the number.

max2010maxim [7]

25 × x = 45

or 25÷100 × x= 45

multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25

therefore, x = 180

( if you use a calculator simply enter 45×100÷ 25)

A pet survey found that the ratio of dogs to cats is 2/5. Write and solve a proportion that shows the number of dogs

Irina18 [472]

So,

The ratio of dogs to cats:
$\frac{2}{5}$

The other proportion:
$\frac{x}{140}$

$\frac{2}{5} = \frac{x}{140}$

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1
$\frac{2}{5} * \frac{28}{28} = \frac{56}{140}$

There are 56 dogs when the number of cats is 140.
