Answer:
b=12
Step-by-step explanation:
To solve this equation, we need to get b isolated on one side of the equation. Perform the inverse operation to both sides of the equation.
1/3b=4
1/3 and b are being multiplied (1/3 * b=1/3b). The inverse of multiplication is division. Divide both sides by 1/3.
1/3b / 1/3= 4/ 1/3
When dividing by a fraction, you can multiply by the reciprocal of the fraction. To find the reciprocal, flip the numerator (top number) and denominator (bottom number).
1/3--> 3/1=3
3*1/3b= 4*3
b=4*3
b=12
Let's check our solution. Substitute 12 in for b in the original equation.
1/3b=4
1/3*12=4
4=4
The statement above is true, so we know our solution is correct.
