What is the difference between \( 8 / 10 \) and \( 4 / 10 \) ?

The difference between \( 8 / 10 \) and \( 4 / 10 \) can be calculated by subtracting the two fractions: \[ (8/10) - (4/10) = (8 - 4) / 10 = 4 / 10 = 2 / 5 \] What this means in simpler terms is that when you take \( 8/10 \) (which is equal to 0.8) and subtract \( 4/10 \) (equal to 0.4), you end up with \( 4/10 \) which simplifies to \( 2/5 \). In practical scenarios, you might use this information to compare quantities such as measuring ingredients in a recipe or splitting costs among friends. Imagine splitting a pizza: if one friend eats \( 8/10 \) of it and another \( 4/10 \), the difference tells you how much more the first friend enjoyed their slice!
