The sum of a and B is 162.8. If the decimal point of B moves one place to the right, it is equal to A. how many are a and B?
Let B be x, a be 10x, 10x + x = 162.8, & nbsp; 11x = 162.8, & nbsp; & nbsp; & nbsp; X = 14.8, a be 10x = 10 × 14.8 = 148
The sum of a and B is 45. After the decimal point of a moves one place to the right, it is exactly twice that of B. how did a use the mathematical formula
How do the fourth grade students answer
A = 45 / (1 + 10 / 2) = 45 / 6 = 7.5
Or let a be x, then B be 10x / 2 = 5x
x+5x=45
x=7.5,
B = 5x = 37.5
