Consider the long division problem below. What error did Sam make when he computed the answer?

-63

0.043) -0.

-0.2709

- 258

129

- 129

• The answer should be -8.3. Sam should have moved the decimal point 3 places to the right in both the divisor and

the dividend.

O The answer should be -630. Sam should have moved the decimal point 5 places to the right in both the divisor

and the dividend.

O The answer should be -65. Sam made an error subtracting 258 from 270.

O The answer should be -61. Sam made an error when multiplying 6 times the divisor.

The answer should be -8.3. Sam should have moved the decimal point 3 places to the right in both the divisor and the dividend.

Step-by-step explanation:

(-0.2709 ÷(0.043)  + (-258÷ 129)

When we move the decimal point towards right we multiply both the denominator and numerator by 1000

(-0.2709*1000 ÷ 0.043*1000) + (-258÷ 129)

= (- 270.9 ÷ 43 ) + (-2)

= -6.3 + (-2)

= -8.3

The answer should be -8.3. Sam should have moved the decimal point 3 places to the right in both the divisor and the dividend.

When we multiply the numerator and denominator with the same number we get the same number as the original number.

The underlying concept of this question tells that the same operations of multiplication must be done to a fraction ( both numerator and denominator) to get the same result as the original fraction would give.
