Number 4 is C because when you do 28 times 5 your get 140 then you do 140 divided by 20 to get 7 when you do proportions to find the missing number you cross multiply with the numbers there and divide with the number that is across from the missing
Number 5 is $6 because to find the missing number you have to see which way makes sense you could do 4 divided by 3 but you get a really long number so if you do 3 divided by 4 you get .75 and you get .75 for all cost is usually the y-axis so you do y divided x so then do .75 times 8 to get the answer
Number 6 to plot them you just go in the middle of the line for the first because it is not directly 2
Number 7 to change a fraction to decimal do the numerator divided by denominator even if the denominator is bigger so 6 divided by 25 is .24 for decimal form to get the percent move the decimal point two places to the right so it will be 24%

Answer:

1) C. 7

2a) $10.66

2b) plot each price and amount at the correct spot

3a) 0.24

3b) %24

Step-by-step explanation:

1) cross multiply the equation: 5*28 =140 and m*20=20m

tun the answers back into an equation: 20m=140

divide both sides by 20: m=7

2a) divide 3 by 2.25: 3/2.25=$1.33(repeating)

divide 4 by 3: 4/3.00=$1.33(repeating)

divide 6 by 4.5=$1.33(repeating)

(because now you know that 1 box of Mac N' Cheese is $1.33) multiply 8 by 1.33(repeating):8*1.33(repeating)=$10.66

3a) divide 6 by 25: 6/25= 0.24

3b) multiply 0.24 by 100: 0.24*100= %24
