Choose the best answer for the missing number
57. 237 =5 x 10+7 x1+2 x(1/10)+3x___+7x(1/1000)
A. 10
B. 1
C. 1/100
D. 1/10
The correct answer is C. 1/100.
To find the missing number, we need to evaluate the given equation.
The equation 57.237 = 5 * 10 + 7 * 1 + 2 * (1/10) + 3 * ___ + 7 * (1/1000) can be rewritten as:
57.237 = 50 + 7 + 0.2 + 3 * ___ + 0.007
To find the missing number, we need to simplify the equation:
57.237 = 57.207 + 3 * ___
To isolate the missing number, we subtract 57.207 from both sides of the equation:
57.237 - 57.207 = 3 * ___
0.03 = 3 * ___
To find the missing number, we divide both sides of the equation by 3:
0.03 / 3 = ___
The missing number is 0.01, which is equal to 1/100.
Therefore, the best answer for the missing number is C. 1/100.
