If US$1.00 is equivalent JA $75.00, What amount, in US dollars is equivalent JA $3300.00

emmasim [6.3K]

Answer:

It is US $44.00 Equivalent

Step-by-step explanation:

Using ratios (essentially fractions):

1 US : 75 JA

OR

1 US = 75 JA

Dividing both sides by 75 gives us:

$\frac{1}{75}$ US = 1 JA

So if we have 3300 JA we can multiply both sides to get:

44 US = 3300 JA
