To solve this problem, we will follow these steps:
Now, let's work through the solution:
Step 1: Multiply both 15.5 and 0.5 by 10 to eliminate the decimals.
Step 2: Divide the resulting whole numbers:
Step 3: We check the result against the choices. The result corresponds to choice 1.
Therefore, the solution to the problem is .
Solve the following exercise:
Multiplying both the dividend and divisor by the same number doesn't change the answer! It's like simplifying a fraction - gives the same result.
Always look at the number with more decimal places! If dividing by 0.25, multiply both numbers by 100 to clear both decimal places completely.
Never! Ignoring decimals changes your numbers completely. 15.5 ÷ 0.5 is very different from 155 ÷ 5 without proper conversion.
Count the decimal places in both numbers. Use the power of 10 that moves the decimal point enough places to make both numbers whole. For 0.5, that's 10¹.
Double-check your multiplication step! Make sure you multiplied both numbers by the same power of 10. Then verify by multiplying your answer by the original divisor.
