Question

I suck at math I could really use some help

Answer 1

Ok so when I was learning that, we used this trick- keep it, change it, rearrange it. So, let’s say for example, 7/10 divided by 3/10. So we keep the 3/10 like it is, we change from division to MULTIPLICATION, and change the 7/10 to 10/7 (rearrange). Now, you have 3/10 x 10/7. Multiply the top numbers (3x10=30) and then the bottom numbers (10x7=70). You simplify so you get 30/70, or 3/7. Let me do one of yours. 27/50 divided by 3/5. Keep it (27/50), change it (division to multiplication) and rearrange it (5/3). So now, 27/50 x 5/3. Multiply the top numbers (27x5= 135) and the bottom numbers (50x3= 150) to get 135/150, or 9/10. Hope I helped you!

Answer 2

1. Because it's a division problem, we can swap the numerators and denominators:

10/12 * 4/3 = 40/36 = 20/18 = 10/9

2. 14/15 * 6/1 = 84/15 = 28/5

3. 9/20 * 10/7 = 90/140 = 9/14

4. 7/12 * 25/14 = 175/168

5. 22/30 * 5/4 = 110/120 = 11/12

6. 30/36 * 4/1 = 120/36 = 40/12 = 10/3

7. 13/15 * 5/2 = 65/30 = 13/6

8. 24/34 * 8/3 = 192/112 = 96/56 = 48/28 = 12/7

9. 36/42 * 7/4 = 252/168 = 126/84 = 63/42 = 21/14 = 3/2

10. 27/50 * 5/3 = 135/150 = 27/30 = 9/10
