1/5 of the number of children in the village have been vaccinated against polio.if 50 children have been vaccinated, find the number of children in the village
(1/5)x = 50
x = 50 / (1/5)
x = 50 * (5/1)
x = 250
250
To find the total number of children in the village, we need to determine the whole, from which the 1/5th portion has been vaccinated.
Let's set up the equation:
1/5 of the total number of children = number of vaccinated children
Let's represent the total number of children as 'x':
1/5 * x = 50
Now, let's solve for 'x'.
Multiply both sides of the equation by 5 to cancel out the fraction:
1/5 * 5 * x = 50 * 5
On the left side, 5 and 1/5 cancel out, leaving only 'x':
x = 50 * 5
Finally, calculate the right side of the equation:
x = 250
Therefore, there are 250 children in the village.
