To multiply a fraction by a whole number, remember that multiplication is repeated addition.
Example
Multiply 1/7 * 3
Write the multiplication as an addition. Add 1/7 three times. Remember you can do this using fraction times number calculator online.
1/7*3=1/7+1/7+1/7
Now we just need to add fractions with like denominators. Keep the denominators the same, and add the numerators.
=(1+1+1)/7=37
