Question

If a number increased by 4.6 is equal to 12, what is the original number?

a) 7.4
b) 12
c) 16.6
d) 8.4

Answer 1

The original number can be found by subtracting 4.6 from 12.

Step-by-step explanation:

To find the original number, we need to subtract 4.6 from 12. Let's call the original number 'x'. So, x + 4.6 = 12. To isolate x, we subtract 4.6 from both sides of the equation: x + 4.6 - 4.6 = 12 - 4.6. Simplifying, we get x = 7.4. Therefore, the original number is 7.4.
