These types of problems are usually just trial and error.
4 x ( 4 - 4/4 ) = 4 x ( 4 - 1 ) = 4 x 3 = 12
-12
False, they're rarely equal. GCF of 12 and 4 is 4 LCM of 12 and 4 is 12
54 4 * 12 = 48
6/12 - 4/16 is equal to 1/2 - 1/4 and that is equal to 1/4
No, 12 to 15 and 4 to 5 are not equal. To determine if two ratios are equal, you need to simplify them to their simplest form. In this case, 12 to 15 simplifies to 4 to 5, so they are equal. However, 4 to 5 cannot be further simplified, so it is not equal to 12 to 15.
no 1/4 = 0.25 4/12 = 0.33333 but, 1/4 is equal to 3/12
12
12
6+6=12 12-8=4
48/12 = 4/1 or 4
x/4 = 12 so x = 4 x 12...
12.25 = 12 1/4.
