Division with Unit Fractions & Whole Numbers

Think what number I can multiply by 8 to get 32, and then use the multiplication fact to find the answer. 8 × 4 = 32, so 32 ÷ 8 = 4.

Inside a square, I drew 3 rows and colored one of the rows green to represent [ggfrac]1/3[/ggfrac]. I drew 5 columns and colored three of the columns blue to represent [ggfrac]3/5[/ggfrac]. The answer is represented by the part of the square where the colors overlap. The answer is [ggfrac]3/15[/ggfrac].

[ggfrac]3/32[/ggfrac] of the back yard.

Ravi is not correct. He multiplied both the numerator and denominator of [ggfrac]2/3[/ggfrac] by 5. He should have just multiplied the numerator by 5, so the answer is [ggfrac]10/3[/ggfrac].

You can draw a circle to represent 1 and divide it in half. Each part represents [ggfrac]1/2[/ggfrac]. So you have two [ggfrac]1/2[/ggfrac]s. You keep drawing halves until you have five [ggfrac]1/2[/ggfrac]s. You find that [ggfrac]1/2[/ggfrac] × 5 = [ggfrac]5/2[/ggfrac] , so [ggfrac]2/5[/ggfrac] is the wrong answer.

You need to solve the equation 3 ÷ [ggfrac]1/2[/ggfrac] = ? Draw 3 circles to represent the 3 cups of milk. Each circle is divided in half and each half represents the [ggfrac]1/2[/ggfrac] cup of milk you need for each cake. You can count to find the number of half cups of milk you have. You have 6 half cups of milk. You can make 6 cakes.

I need to find the answer to 2 ÷ [ggfrac]1/4[/ggfrac] = ? First, I convert the division problem into a multiplication problem: 2 × 4. 2 × 4 = 8. I can make 8 birdhouses with the 2-yard-long wood board.

[ggfrac]1/3[/ggfrac] ÷ 2 = [ggfrac]1/6[/ggfrac] . Each small piece is [ggfrac]1/6[/ggfrac] of the pie.

[ggfrac]1/6[/ggfrac] yard.

Delroy is not correct. To find the answer, you need to solve the equation 8 ÷ [ggfrac]1/4[/ggfrac] = ? To divide 8 by [ggfrac]1/4[/ggfrac], you change the division equation into the multiplication equation 8 × 4 = ? 8 × 4 = 32, so there are 32 one-fourth pieces.
