The sum of a and B is 31.24. If the decimal point of a is moved one place to the left, it is equal to B. what are the two numbers?
Number of a: 31.24 ÷ (1 + 0.1) = 28.4
Number B: 28.4 △ 10 = 2.84
The sum of a and B is 24.2, and the decimal point of a moves one place to the left, which is exactly equal to B. what are the two numbers?
We don't need to solve the equation, we use the formula
A is 10 times as much as B. isn't 24.2 divided by 11 b
