4 0

Answer:

1:4

Step-by-step explanation:

If 8/10 prefer Crest, that means 2/10 don't prefer it.

To find the ratio, put together the number that don't prefer it to the number that does:

2:8

Simplify by dividing each side by 2:

1:4

So, the ratio is 1:4

Laura has a step of 50cm She walks along by taking two steps forward and one step back. What is the least number of steps counti
Vilka [71]

Answer:

The least number of steps she takes to reach 20 m is 118 steps

Step-by-step explanation:

For Laura, the length of a walking step = 50 cm = 0.5 m

The repeating number of steps she takes = Two steps forward one step backwards

The number of forward steps it would take for her to reach 20 m = (20 m)/(0.5 m) = 40 steps

Given that she always takes two steps forward and one step backwards, we have;

The number of steps forward every three steps = 2 step forward + (-1) step (backward)

The number of steps forward every three steps = 2 - 1 = 1 step forward

To reach 39 steps forward, she would need 39 × 3 =  117 steps

To get to the 40 steps she needs just a step forward, making the total number of steps to reach 40 steps = 117 + 1 = 118 steps

Therefore, the least number of steps she takes to reach 20 m = 118 steps.
