Question

Why can you use cross products to solve the proportion StartFraction 18 over 5 EndFraction = StartFraction x over 100 EndFraction for x?
options:
because 18 times 100 is equal to 5 times x, which means that x is equal to 36

because 18 times 100 is equal to 5 times x, which means that x is equal to 360

because 18 times x is equal to 5 times 100, which means that x is equal to 36

because 18 times x is equal to 5 times 100, which means that x is equal to 360

Answer 1

\[\frac{ 18 }{ 5 } = \frac{ x }{ 100 }\]

so than you see it now what will get using cross products ?

Answer 2

cross multiplie what will get ?
