C. x+10
The ratio is the relation between numbers. 40/100 is simplified to 4/10 (40%)
C because it says no more not equal too
9+8=8+9 the trick for commutative is there are two m's in commutative right? well no matter where the mm's are it is still the same word so just like the answer is still the same where ever they go.
The answer is 6.7
You (should) know 10 goes into 67, 6 times. So write 6 on the top and subtract 60 from 67. You get 7. 10 doesn't go into 7 because 7 is less. So write a zero next to the 7 AKA bring down a 0. You will then technically have 70. 10 goes into 70, 7 times, so write 7 next to the previous 6 at the top, and put a decimal between 6 and 7.
Or
You should know if anything is being divided by 10. You just move the decimal to the left. Left is less. In 67 the decimal is right after the 7. 67.0. Therefore if you move the decimal one place over to the left you get 6.7
Either way works.
