How you explain depends on your knowledge and that of the person tat you are trying to explain to.
Start with the ratio of the integers 4 and 5 which is 4 over 5 or 4/5.
If you separately multiply the numerator (4) and the denominator (5) by the number 2 you get 4*2 = 8 and 5*2 = 10
The ratio of these two numbers is 8/10 but because of the way you obtained these numbers, the ratio has the same value. That is, also the same as 4/5.
Multiply both part of the original ratio by 3 to get 12/15.
You can multiply the two numbers by any non-zero number to get an equivalent ratio although if you multiply by a fractional number, the results may be a bit hard to understand. For example, multiplying by 1/16 gives the ratio of 1/4 over 5/16. Not so easy to see the equivalence to 4/5 unless you know that dividing by a fraction is the same as multiplying by its reciprocal.
To find what is equivalent to 12 over 40, we need to simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 4. This simplifies the fraction to 3 over 10. Therefore, 3 over 10 is equivalent to 12 over 40.

80/100 8/10 12/15 20 over 25 8 over 10 12 over 15
12/5 = 10 2/5
10 over 12Any multiple of 5 over that same multiple of 6. In other words, 5*X / 6*Xfraction which is equivalent to 5 over 6 = 10/12
Because both 10 and 12 will divide exactly by 2. Therefore the equivalent to 10/12 is 5/6
They are equivalent.
No.
To find what is equivalent to 12 over 40, we need to simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 4. This simplifies the fraction to 3 over 10. Therefore, 3 over 10 is equivalent to 12 over 40.
No. 6/8 = 0.75, 10/12= 0.83
10/12 is also equivalent to 20/24, 30/36, and 40/48
12/5 is equivalent to 24/10
8 over 10 (8/10) and 12 over 15 (12/15) are equivalent to 4 over 5 (4/5).
