Chen completed the division problem below.

0.9 StartLongDivisionSymbol 192.6 EndLongDivisionSymbol right arrow 9 StartLongDivisionSymbol 192.6 EndLongDivisionSymbol minus 18 = 12. 12 minus 9 = 36. 36 minus 36 = a remainder of 0 and a quotient of 21.4.

What is Chen’s error?
He included a 4 in the quotient, which does not belong.
He multiplied the dividend by 100 instead of 10.
He should have multiplied both numbers by 100.
He did not subtract correctly in one of the steps.

$15 each

step-by-step explanation:

$45/3 children= $15 each

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
