Mr. Lutor wants to explain how to use a shortcut method (that is, without using a calculator). To calculate how much money he must pay it is proposed: I. Convert the mixed number into an improper fraction

II. Multiply the improper fraction by 100%

III. Multiply the improper fraction by 1/100 and 76

IV. Simplify the fractions

V. Add the found value with 76

The proposal that DOESN´T allow calculating the total of money he must pay is:

NUMBER: 17 1/2

answer: dead jah

step-by-step explanation:

bullet + jah= dead jah

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

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
