Answered by Ms. Sue
You can check them by substituting your value for the unknown in the original problem.

In your first problem, does 2 * 1 1/7 = 4/7? No. Try again.

for problem
2t = 4/5
heres what it did:
2t = 4/7
*2 = *2 4/7 * 2/1 = 8/7 = 1 1/7
t = 1 1/7
Answered by Ms. Sue
2t = 4/7

t = (4/7) / 2

t = (4/7) * (1/2

t = 4/14

t = 2/7

Does that check out when you substitute 2/7 in your original problem? Yep!
Answered by marko
yes 2/7 is right - i get now
so
r/6 = 8
i got r = 48 is correct right?

2b/9 = 4
i got: b = 13 right?

3y = 4/5
y= 4/15 right?


5g = 5/6
got : g = 1/6 right?

3k = 1/9
i got: k = 1/27 right?

3x/5 = 6
i got x = 10 right?
Answered by Ms. Sue
This is wrong.

2b/9 = 4
i got: b = 13

The others are right.
