   5           x

In a proportion, u cross multiply. Take the denominator of the first fraction and multiply it by the numerator of the second fraction. Then take the numerator of the first fraction and multiply it by the denominator of the second fraction.

(5)(3) = (1)(x) ...now multiply
15 = x

and u will see from the answer   1/5 = 3/15 that these are equivalent fractions because that is all proportions are..they are just equivalent fractions.

Here is another one...
2/11 = x/22 .....cross multiply
(11)(x) = (22)(2)
11x = 44
x = 44/11
x = 4

2/11 = 4/22.....equivalent fractions

Use the formula, I = PRT, to find the time if | = $387.50, P = $1,550, and R = 12.5%
stiks02 [169]

Answer:

T = 2

Step-by-step explanation:

Take the given formulaer

I = PRT

And plug in the variables you know (I, P, R)

387.50 = 1,550(.125)T

(12.5% becomes .125 after you divide it by 100, because precents are really just fractions out of 100)

387.50 = 193.75T

T = 2

Which one of the following is an ordered pair?
valentinak56 [21]

9514 1404 393

Answer:

  (c)  (0, 6)

Step-by-step explanation:

Conventionally, an "ordered pair" is a pair of items in parentheses, separated by a comma. The items don't have to be numbers. (0, 6) is an ordered pair.

__

<em>Comments on the other answer choices</em>

Curly braces are usually used as delimiters of a set, not an ordered pair.

Three items do not constitute a "pair." Rather, they are a "triple."

Items without any particular indicator of grouping are usually not considered a "pair."
