Question

write each expression as a decimal.

1. two hundred fifty - one thousandths
2. one and eleven hundredths
3. eight hundredths
4. seventy and fifty - six thousandths
5. five hundred and two ten - thousandths
6. thirty - six ten - thousandths

Explanation:

Problem 9: two hundred fifty - one thousandths

Step 1: Recall place value

Thousandths place is the third decimal place. So we can write two hundred fifty - one as 251 and since it's thousandths, we divide by 1000.
$\frac{251}{1000}$

Step 2: Convert fraction to decimal

Dividing 251 by 1000, we move the decimal point three places to the left. So $251\div1000 = 0.251$

Step 1: Analyze the parts

"One" is the whole number part, which is 1. "Eleven hundredths" means 11 divided by 100.
$\frac{11}{100}$

Step 2: Convert and combine

$\frac{11}{100}=0.11$. Then we add the whole number part: $1 + 0.11=1.11$

Step 1: Recall place value

Hundredths place is the second decimal place. So eight hundredths is 8 divided by 100.
$\frac{8}{100}$

Step 2: Convert fraction to decimal

Dividing 8 by 100, we move the decimal point two places to the left. So $8\div100 = 0.08$

Answer:

0.251

Problem 10: one and eleven hundredths
