Star at -20 and go back by -5 on the number line
Adding rational numbers involves adding decimals and repeating decimals like 4.6666666..... Whole numbers on the other hand involves adding 7+6 which arent exactly decimals
A) tomatoes : chicken broth = 9:15 or 3:5
Tomatoes : spinach = 9:9 = 1:1
Spinach : chicken broth = 9:15 = 3:5
b) tomatoes : chicken broth = 4.5:7.5 = still 3:5
Tomatoes to spinach is still 1:1
Spinach : chicken broth 4.5:7.5 still = 3:5
Dividing all quantities by 2 doesn’t change the ratio.
Explanation:
Step 1) Add
4
to each side of the equation to isolate the
x
term while keeping the equation balanced:

Step 2) Divide each side of the equation by
12
to solve for
x
while keeping the equation balanced:
