To compare the amounts of gasoline Angel and Miguel have, let's represent their amounts on a number line.
Angel has 3/8 a tank, so we can mark 3/8 on the number line. Miguel has 7/8 so we mark 7/8 on the number line as well.
Let's draw a number line from 0 to 1 and mark 3/8 and 7/8 .
0 ----------------------- 3/8--------------------------7/8 Looking at the number line, we can see that 7/8 is farther to the right than 3/8. Therefore, Miguel has more gasoline than Angel.
