When subtracting, if the fraction in the first number is larger than the fraction in the second number, you can subtract directly. For instance, (4 \frac34 - 1 \frac14).
Don't skip the drawing portion of the homework. Tape diagrams and number lines create mental math pathways that prevent careless calculation errors later on.

Convert improper fractions to mixed numbers if requested by the module instructions. When subtracting, if the fraction in the first
Some problems ask students to draw a tape diagram to represent the multiplication expression. Draw a tape diagram to represent
The primary answer resulting from the division process.
This strategy involves converting the mixed number into a format that makes direct subtraction easy. Take 1 away from the whole number.

Thus, (1 \frac25 + 2 \frac35 = 4). If the fraction sum is less than 1, you simply keep it as a fraction next to the whole number.
In , students learn to subtract a fraction from a mixed number using various strategies like number lines, the arrow way, and decomposition. 1. Subtract Using the Arrow Way or Number Line
Use graph paper or turn a piece of lined notebook paper sideways. Keeping your hundreds, tens, and ones places perfectly aligned prevents simple computational errors.
