Simplify the following ratios:
8:12
4:8
2:10

2:3 1:2 1:5

Step-by-step explanation:

As you can see each of these are divisible by two. So just divide eache number in the ratio by two. If they are both STILL divisible by two then just divide them both by two again.

Ex: 8:12  8 divided by two is 4          4:6  Divide again to get 2:3

               12 divided by two is 6

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
