Question

Which techniques can be used to evaluate the expression 12.75 ÷ 1.5 ? Select ALL that apply.

Answer 1

Answer:

Answer = 8.8

Step-by-step explanation:

1. We'll first write the above decimal numbers in fractional form.

$12.75 \div 1.5 \\ \\ = \frac{1275}{100} \div \frac{15}{10}$

ㅤ

ㅤ 2. Now we'll divide it further.

$\frac{1275}{100} \div \frac{15}{10} \\ \\ = \frac{1275}{100} \times \frac{10}{15} \\ \\ = \frac{1275}{10 \times 15} \\ \\ = \frac{255}{10 \times 3} \\ \\ = \frac{88}{10}$

ㅤ

ㅤ3. And finally, we'll write our quotient in decimal form.

$\frac{88}{10} \\ \\ = 8.8$

ㅤ

Hence evaluated.

Answer 2

Answer:

$12.75 \div 1.5 \\ \\ = \frac{12.75}{1.5} \\ \\ = \frac{12.75}{1.5} \times \frac{100}{100} \\ \\ = \frac{1275}{150} \\ \\ = \frac{85}{10} \\ \\ = 8.5$
