They are: 13 to 15 and 39 to 45
13:15 is the answer
3:8 is equivalent to 6:16 or 30:80 or 30000:80000
5/10 = 1/2 write the proportion as ratios 5:10 = 1: 2 5/10 = 10/20 or 5:10 = 10:20 5/10 = 15/30 or 5:10 = 15:30
Many 'fractions' can be easily created using ratios of multiples of 30: Multiples:30 60 90 120 150 . . . Ratios:30/1, 60/2, 90/3, 120/4, 150/5 . . .
52 to 2 i think i had it on a test once
15/6=30/12=35/14=5/2 for example. Any fraction of the form 5n/2n where n is a whole number will produce an equivalent fraction, read ratio, to 15/6.
13 to 15 39 to 45
30/110 and 3030/1111 are two equivalent ratios.
The equivalent ratios of 3 and 4 are 6:8, 9:12, and 15:20.
30 to 12 45 to 18
1 to 5 and 3 to 15
They are: 6/30 and 1/5
7/15 = 14/30 = 70/150
No.
5 to 6 10 to 12 15 to 18
10:30, 20:60, 15:45 are three possible ratios
There are 26/30 and 13/15 (examples)
Multiply both numbers of the ratio, 30 to 11, by any non-zero number. You will have an equivalent ratio.
