Question

what number can i combine with 0.30 to make 1 whole? first, complete the sentence. i can think about 0.30 as 30? ^ cents dollars

Explanation:

Step1: Analyze the unit for 0.30

Since 1 dollar = 100 cents, 0.30 dollars would be 0.30 * 100 = 30 cents. So 0.30 is 30 cents.

Step2: Find the number to make 1 whole (1 dollar or 100 cents)

Let the number be \( x \). We know that \( 0.30 + x = 1 \). Solving for \( x \), we get \( x = 1 - 0.30 = 0.70 \). In terms of cents, 100 cents - 30 cents = 70 cents, which is 0.70 dollars.

Answer:

For the first part (completing the sentence), the answer is cents. For the number to combine with 0.30 to make 1 whole, the number is 0.70 (or 70 cents).
