Answer:
Step-by-step explanation:
10/7 x 9/8 = 90/56 = 45/28.
7/9 x 8/10 = 56/90 = 28/45
If you want to multiply these, the answer is (28*45) / 28/45) = 1.
Yes. it would be 1 and 18/30 or 1 9/15. it can also be 1 and 3/5 or 8/5
Let us pretend x is the number.
The equation will be 13-6x=11+4x.
Solve.......
X=2/10
It's C.
multiply by 3
x = 4, y = 4x3 = 12
x = 5, y = 5x3 =15
x = 6, y = 6x3 =18
