A boy spent 5/6 of his money and had 100 naira left how much did he spend
well, he spent 5 times as much as he had left, right?
The boy has X nairas.
X - 5x/6 = 100,
Multiply both sides by 6:
6x - 5x = 600,
X = 600,
(5/6) * 600 = 500 Nairas spent.
To find out how much the boy spent, we need to work backwards.
Let's assume the total amount of money the boy had originally was "x" naira.
The boy spent 5/6 of his money, which is (5/6)x.
We know that after spending this amount, he had 100 naira left.
So, we can write the equation:
(5/6)x + 100 = x
To solve for x, we need to clear the fraction by multiplying both sides of the equation by 6:
6 * (5/6)x + 6 * 100 = 6 * x
5x + 600 = 6x
Now, subtract 5x from both sides:
600 = x
Therefore, the boy originally had 600 naira.
To find out how much he spent, we can substitute this value back into the equation:
(5/6) * 600 = 500
Therefore, the boy spent 500 naira.
