Answer:
D: 5 : 8 and 20 : 32
Step-by-step explanation:
A is incorrect because 3 x 1.33 = 4 and 4 x 1.25 = 5.
B is incorrect because 10 x 1.6 = 16 and 12 x 1.5 = 18.
C is incorrect because 7 x 1.428 = 10 and 10 x 1.4 = 14.
D is correct because 5 x 4 = 20 and 8 x 4 = 32.
another way of solving the ratio answers is by putting them in a fraction 5/8 = .625 and also does 20/32 = .625.....
Easy right!?

Answer:
102
Step-by-step explanation:
The least common multiple of 6 and 17
For us to determine the L.C.M of 6 and 17,
First find the prime factors of 6 and 17
Prime Factor of 6
6 = 2 × 3
Prime factor of 17
17 = 1 × 17
Secondly;
Multiply all the factors together to find the L.C.M:
L.C.M = 1 × 2 × 3 × 17
L.C.M = 102
