Do the ratios 10 8 and 5 2 form a proportion? yes or no

No

Step-by-step explanation:

pretend that the larger number in the ratio is always 60

10:8 so 10=60

60÷10 =6

6x8=48

so in 10:8 10=60 and 8=48

60-48= 12

in 5:2

5=30

2=12

30-12=18

10:8 and 5:2 when substituted to a real number will not have the same difference so they are not a proportion

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8
