Just as in the case of a fraction, you can expand such a ratio by multiplying both numbers with the same non-zero number. It's easiest if you use integers for this.
It is sin(-x) = -sin(x)
To compare we have to calculate the ratios in simplest form. The ratios of 6 /8 =3/4.and 8/10 =4/5 . and we can say 4/5 is not equal to 3/4.
3 equivalent ratios for 4:8 are 75:150, 50:100 and 3:6
4 ratios equivalent to 75% are....3/4, .75, 3/40, AND 7.5
no they are not
The equivalent ratios of 3 and 4 are 6:8, 9:12, and 15:20.
3 to 4
No
3 to 4
It is 2 and 3
It is: 1/3 = 2/6
An equivalent fraction cannot be derived from an integer. But if the 31 happens to be 3:1, possible equivalent ratios are 6:2, 9:3, 12:4
If you mean: 12 to 3 then it is equivalent to 4 to 1
