Question

3 x 10 + 2 x 1 + 6 x 1|100 + 4 x 1|1,000 is the expanded form of which decimal?​

Answer 1

6 × 1 + 3 ×(1/100) + 9 × 10 + 2 × (1/10)

We know that 1, 1/100, 10, and 1/10 are place values. We can write 14.25 as 1 × 10 + 4 × 1 + 2 × (1/10) + 5 × (1/100), for example. We can use that information to solve the above.

We also can multiply and add the expression.

6 × 1 + 3 ×(1/100) + 9 × 10 + 2 × (1/10)

6 + 3/100 + 90 + 2/10

6 + 0.03 + 90 + 0.2

96.23
