Answer:
x is 50.
Step-by-step explanation:
3.5 and 1.4 are both at the bottom of the fraction (denominators), so divide 3.5 by 1.4 to get 2.5.
Then, multiply 20 by 2.5.
This makes sense because 3.5 is greater than 1.4, and the final answer (50) is greater than 20.
We can always check by dividing 50 by 3.5 and 20 by 1.4. See if it is the same number.
