The number is 49
Step-by-step explanation:
Let the number be x
From the question,
Multiply both-side of the equation by 7
(On the left-hand side of the equation, 7 at the numerator will cancel-out 7 at the denominator leaving us with just 3x)
3x = 147
Divide both-side of the equation by 3
(On the left-hand side of the equation 3 at the numerator will cancel-out 3 at the denominator, while on the right-hand side of the equation 147 will be divided by 3)
x =
x=49
Therefore the number is 49
