Question

write the ratio as per percentage 3:4:8 with method ​

Answer 1

Answer:

We can think of this ratio as two smaller ratios: 3:4 and 4:5. If 27 is the 3, we have: 3:4 = 27:x, with x being the denominator.

We can simplify this: 1:4 = 9:x. Cross multiplying gets us x = 36.

Now we can use the 36 to get the last number; we'll call it y. We have the equation: 4:5 = 36:y.

Simplifying this gets us 1:5 = 9:y. Cross multiplication once again gets us: y = 45.

The last two numbers of the ratio 3:4:5 with the smallest number equal to 27 are 36 and 45.

Answer 2

3:4:8 according to percentage

= 3/15 × 100

= 20%

= 4/15 × 100

= 26.66%

= 8/15 × 100

= 53.33%

= 20% : 26.66% : 53.33%
