Question

decide whether each expression is less than 100 or greater than 100.
less than 100
$9 \div 0.1$
greater than 100
$18 \div 0.1$
$11 \div 0.1$

Explanation:

Step1: Calculate $9\div0.1$

Dividing by 0.1 is multiplying by 10: $9\div0.1 = 9\times10 = 90$

Step2: Calculate $18\div0.1$

$18\div0.1 = 18\times10 = 180$

Step3: Calculate $11\div0.1$

$11\div0.1 = 11\times10 = 110$

Step4: Compare to 100

Classify results against 100.

Answer:

Less than 100:

$9\div0.1$

Greater than 100:

$18\div0.1$, $11\div0.1$
