What is 24:28=? 250:400=? 270:30=? 4:80=? 55:33=? 1000:100=? 560:80=? 20:340=? Plz help ill give u 20 points if u do all of these:)

Step-by-step explanation:

Ok so if you didn't know, : is another way to write / so 24:28 is the same thing as 24 divided by 28. Or if you just wanted to simplify to most, you just want to find the largest common factor and divide it by both.

24:28 = 6:7

250:400 = 5:8

270:30 = 9:1

4:80 = 1:20

55:33 = 5:3

1000:100 = 100:10

560:80 = 7:1

20:340 = 1:17

24:28= 6:7

250:400= 5:8

4:80= 1:20

55:33= 5/3

1000:100= 10:1

560:80= 7:1

20:340= 1:17

Step-by-step explanation:

Divide the numbers on each side of the ratio by Common Factors until what's left can't be divided any further.

One example, last one:

20:340 both divisible by 10, so you get 2:34. Both even numbers so divide by 2. You get 1:17. They can't be divided any further to get whole numbers, so that's the answer.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
