Answer:
Step-by-step explanation:
Take a look at the place value chart.
A. Is a whole number, so it would be to the left of the decimal place. The 4 is in the thousands place.
B. Looking at the chart, B is .738 noticed that the 7 is in the tenths place.
C. The 2 is in the tenths place.
D. The 1 is in the tenths place.
Therefore the answer is B.
Please memorize this chart. It's going to be important for everything you do in math.

Answer:
0.80A + 0.92B = 63 .....1
A + B = 75 ......2
Step-by-step explanation:
Let A and B represent the total possible score in part A and B respectively;
Analysing each sentence of the question;
Sam scored 80% on Part A of a math test and 92% on part B of the math test. His total mark on the test was 63
80% of A + 92% of B = 63
0.80A + 0.92B = 63 ......1
The total possible marks for the test was 75;
A + B = 75 .....2
So, equation 1 and 2 provides a set of simultaneous equations that can be used to represent and solve the situation.
Solving the simultaneous equations, we will arrive at;
Part A = 50
Part B = 25
