Ok so this all about subtracting fractions this is what you want to do:
you can change 8 3/4 and 4 2/3 to have the same value and deominator
8 3/4 = 8 9/12(multiply both sides by 3)
4 2/3 = 4 8/12(multiply both sides by 4)
you do this because 12 is divisible by 3 and 4
then, subtract 4 8/12 from 8 9/12 because John is using some of the wood his dad gave him.
then subtract once again, taking 11/2 away from your difference.
again match the deominator of 11/2 to the deominator of your difference which should be 12. another divisible of 12 is 2 and 6.
11/2 = 66/12 = 5 6/12(multiply both the top and bottom by 6)
and start subtracting.
so John should have -1 5/12(?) wood left
The value of k is 60
131 - 11 = 120
120/2 = 60
hope this helped !
Number 7 is C, im not sure about 6 though
Answer:
the aswer is 2
Step-by-step explanation:
this is because 10/5=2
40% means 0.4 .
So . . . . . 7 = 0.4 N .
Divide each side by 0.4 . . . N = 7/0.4 = 17.5
