How is finding 40% of 300 similar to finding 2/5 of 300?

because  40% = 2/5

Step-by-step explanation:

how is finding 40% of 300 similar to finding 2/5 of 300?

because   40 % =  40/100 = 4/10 = 2/5  which is 2/5

and  40% * 300 = (2/5) * 300  

since  (2/5) * 300 = (2/5) * 300

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
