Sure! Let’s solve each of the 16 problems step by step. The goal is to
find the missing number in each subtraction equation involving decimals (with 1 or 2 decimal places).
We’ll use basic algebra:
If `A - B = C`, then:
→ To find A (the minuend): `A = B + C`
→ To find B (the subtrahend): `B = A - C`
