Enter in the missing numbers to create equivalent ratios. 1: 5 ? : 10 5: ? ? : 50

we are given

1:5

to get from 5 to 10, you must multiply by 2

1 x 2 = 2

5 x 2 = 10

2:10

to get from 1 to 5, you must multiply by 5

1 x 5 = 5

5 x 5 = 25

5:25

to get from 5 to 50, you must multiply by 10

1 x 10 = 10

5 x 10 = 50

10:50

hope this helped

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )

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.
