Question

correct or not?

1. 2k = 5/6
k= 5/12?

2.3b= 4/7
b= 4/21?

3. 2/3 d = 5/8
d= 15/16?

4. 2/7 a = 5/8
a= 2 3/16? And do I need to simifly?
all numbers are correct. :)
the last one, 2 3/16, i think it's fine in mixed number form.
1,2,and 3 are right.

4. You need to multiply each side by the opposite. So to cancel out 2/7 on the left side, multiply by 7/2 to get a by itself. Then you have to multiply the right side by 7/2 also. Multiply 5*7 to get the top and 2*8 to get the bottom. Let me know if you need more help.
Noelle how did you get 2 x 8?
Like this:

5/8 * 7/2

So, you multiply the two top numbers (5*7) and the two bottom numbers (8*2) to get the final answer for a.
4 is right. Noelle, 5/8*7/2=35/16=2 3/16, which is what they had for their answer.
Not sure what that says, but if it was inappropriate, the site regulators will have you banned from this site.
