Question

1. higher order thinking use each number below. 1 2 4 5 write the 2-digit subtraction problem that has the greatest difference. then solve.

Explanation:

Step1: Determine the largest and smallest 2-digit numbers

To get the greatest difference in a 2-digit subtraction, we need the largest possible 2-digit number and the smallest possible 2-digit number from the digits 1, 2, 4, 5. The largest 2-digit number is 54 (using the two largest digits, 5 and 4, with 5 in the tens place), and the smallest 2-digit number is 12 (using the two smallest digits, 1 and 2, with 1 in the tens place).

Step2: Perform the subtraction

Now, subtract the smaller number from the larger number: $54 - 12$.
Calculate the result: $54 - 12 = 42$.

Answer:

The subtraction problem is $54 - 12$, and the solution is $42$.
