Multiply the whole number by the top and keep the bottom: 6 × 3/6 = 18/6. It's the same as adding 3/6 six times. Turn it into a whole or mixed number if asked.
unit fractionone equal part, like 1/4
numeratorthe top number: how many parts
improper fractiontop bigger than bottom, like 7/4
mixed numbera whole number and a fraction: 1 3/4
Watch for: Multiplying the bottom too: 6 × 3/6 is not 18/36. Adding the whole number to the top instead of multiplying. Leaving the unit off a story answer, like miles.
At home: Scoop with a 1/4 cup: 6 scoops is 6 × 1/4 = 6/4, or 1 1/2 cups. Pour them into a bigger measuring cup to check.
