To find out how many marbles the boy started with, we can use a simple equation.
Let's denote the number of marbles the boy started with as "x".
According to the given information, the boy lost 0.3 of his marbles, which means he has 77 left.
We can set up the equation as follows:
x - 0.3x = 77
Now, we can solve the equation to find the value of "x".
0.7x = 77
Divide both sides of the equation by 0.7:
x = 77 / 0.7
Now, we can calculate the value of "x" to determine how many marbles the boy started with.
x ≈ 110
Therefore, the boy started with approximately 110 marbles.
.7x = 77
x = 77/.7 = ...
