Answer:
To multiply two fractions, we multiply the numerators to get the new numerator and multiply the denominators to get the new denominator. However, we are taught that when faced with a problem such as 3⁄5 ÷ 4⁄7, we should invert the second fraction and multiply.
The Correct Answer is 60.5 Milliroentgens Per Hour
Ex. 62.5 / 3 = 20.8
2 / 20.8 = 10.4
62.5 - 2 = 60.5
A, sub in a random number as x in all equations and solve, eg- x= 3
2-3= -1
3-2=1
-2 +3= 1
3-2=1
