Emir is creating sewing kits for local high school students who are heading off to college. He has 16 needles and 12 spools of thread, which he wants to divide evenly, with no materials left over. What is the greatest number of sewing kits Emir can make?

4

Step-by-step explanation:

Given that :

Number of needles = 16

Numbe of spools of thread = 12

The greatest Number of sewing kits that can be made is found by obtaining the Greatest Common factor of both number of threads and number of spool of thread;

Factor of :

16 : 1, 2, 4, 8, 16

12 : 1, 2, 3, 4, 6, 12

Hence, the greatest common factor = 4

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

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.
