What is 33 percent of 400

bearhunter [10]

Hi there :)

Answer: 33% of 400 is 132.

I found this answer because I multiplied 400 * 3 which equals 13,200.

then I divide 13,200 by 100 and then you will get your answer of 132.

I hope this helps you if you need any help, feel free to message me.

A photocopier increased the sides of a square in the ratio 4:5.

Svetach [21]

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

$\frac{x}{y} =\frac{4}{5}$

$y=\frac{5}{4}x$

$y=1.25x$

the increase is calculated by subtracting x from y

$y-x=1.25x-x=0.25x$

Remember that

$0.25=\frac{25}{100}=25\%$

therefore

The sides are increased by a percentage of 25%
