Which of the following ratios are equivalent to 4:5?
16/25
12:15
8/10
24/32
36 to 40
16 to 20
PLEASE HELP!
multiply 4 and 5 by the same number (2,3,4,5,...)
which new fractions are given as choices?
"/" or ":" or "to" all mean the same thing --- a ratio
I don't get it oobleck, can you explain more
ok. Start with 4/5
multiply top and bottom by 2, and you get 4/5 = 4*2 / 5*2 = 8/10
That's in the list.
Now just try other values to multiply by.
Oh! Wait! Its 12:15, 8/10, and 16:20! That's the Answer!
To determine if a ratio is equivalent to 4:5, we need to simplify the given ratios and compare them with 4:5.
1. 16/25:
To simplify this fraction, find the greatest common divisor (GCD) of 16 and 25, which is 1. Since there is no common factor to divide, the fraction cannot be simplified further. So, 16/25 is not equivalent to 4:5.
2. 12:15:
To simplify this ratio, find the GCD of 12 and 15, which is 3. Divide both numbers by 3 to get 4:5. Therefore, 12:15 is equivalent to 4:5.
3. 8/10:
To simplify the fraction, find the GCD of 8 and 10, which is 2. Divide both numbers by 2 to get 4:5. Therefore, 8/10 is equivalent to 4:5.
4. 24/32:
To simplify this fraction, find the GCD of 24 and 32, which is 8. Divide both numbers by 8 to get 3:4. Therefore, 24/32 is not equivalent to 4:5.
5. 36 to 40:
To simplify this ratio, find the GCD of 36 and 40, which is 4. Divide both numbers by 4 to get 9:10. Therefore, 36 to 40 is not equivalent to 4:5.
6. 16 to 20:
To simplify this ratio, find the GCD of 16 and 20, which is 4. Divide both numbers by 4 to get 4:5. Therefore, 16 to 20 is equivalent to 4:5.
From the given options, the ratios that are equivalent to 4:5 are:
- 12:15
- 8/10
- 16 to 20
