2/5 of two numbers is 56.One of the numbers is 36.What is the other number?

104

Step-by-step explanation:

Let x = the unknown second number.  2/5 of [the sum of] two numbers is 56. One of the numbers is 36:

(2/5)(36+x) = 56

Multiply both sides by 5/2:

36 + x = 56*5/2

36 + x = 140

x = 104

Check:

(2/5)(36+104)=56

(2/5)(140)=556

280/5 = 56

56 = 56

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
