Question

Do the ratios 4 me to 3 me and 24 cm to 18 cm form a proportion?​

Answer 1

Answer:

yes, they are in proportion.

Step-by-step explanation:

to check proportion, first convert them into the same unit. so

4m * 100 = 400 cm

3m * 100 = 300 cm

now, let's arrange

400:300::24:18

now to find if they are proportional ill give a small tip.

400 and 18 are on the ends

300 and 24 are in the middle.

if let's say the equation is 400:300::x:18

we can multiply both the ends as they both are present. 400*18 = 7200, now divide by 300 = 7200/300 = 24. so now as you see, if you want to find if a given equation is proportional or not, remove any one number from it. multiply the ends if a center piece is removed and multiply the centre if end piece is removed. and lastly, divide the product by the remaining number. if the number you removed = quotient remaining number divided by sum of remaining 2 'partners'.
