Answer:
x=8
Step-by-step explanation:
Cross multiply to solve
2/x=4/16
4*x=2*16
4x=32
Divide by 4 on both sides
x=8
So,
2/8=4/16
Hope this helps! :)
The answer is (4, -1)
x = 4 and y = -1

This is exactly like normal subtraction, but with a fraction instead of an integer. Take one away from 360 and turn it into a fraction: 359 6/6 - 5/6. Now subtract the two fractions: 6/6 - 5/6 = 1/6. Add that to your number: 359 1/6.
Answer:
28
Step-by-step explanation: This should be 28. 42 divided by 3 is 14. Why would you divide it by 3? Because the full ratio is 2:3. So 42 divided by 3 is 14. Then you add fourteen twice, for the two in the ratio. Fourteen plus fourteen is 28.
