Unit fractions are fractions with a 1 as the numerator(number on top)
so 3/8 equals 1/8+1/8+1/8
Answer:
x = 9/4
Step-by-step explanation:
Locate point G on segment DE so that DG = 1 and GE = 4. CG is parallel to AD, so ΔCGE ~ ΔABC. Corresponding sides are proportional.
AB/BC = CG/GE
x/1 = 9/4
x = 9/4
_____
<em>Additional comment</em>
Using the given triangles, you can write the proportion statement as ...
(9+x)/x = 5/1
We judge this to take more steps to solve, so we prefer the method shown above.
You do 3 x 8 / 100 to work out 3/8 as a decimal. So its 0.24. 0.38 is bigger
100 sandwiches, using bun packages of 8...
100/8=12.5 Since you cant buy a half a package, round up to 13 packages
100 sandwiches, using bun packages of 12...
100/12=8.33 Since you cant have a third of a package, round up to 9 packages
A. never
because you are limiting x from 0 to infinite, and all of these are positive.
